Mixmath
{{More citations needed, date=November 2021 mi×ma+h (or Mixmath) is a Canadian board game developed by Wrebbit and published in 1987. It resembles a variant of Scrabble in that tiles are placed on a crossword-style grid, with special premiums such as squares that double or triple the value of a tile and a 50-point bonus for playing all seven tiles on the player's rack in one turn. Unlike Scrabble, Mixmath uses numbered tiles to generate short equations using simple arithmetic. Wrebbit, maker of Puzz-3D jigsaw puzzles, has since been taken over by Hasbro, and it appears that Mixmath has been discontinued. Gameplay Mixmath is designed for 2 to 4 players in games lasting roughly 60 minutes. Players should be comfortable with the basic operations of addition, subtraction, multiplication, and division. Contents The gameboard is a 14x14 grid. The central four squares are orange and contain the numbers 1 (upper left), 2 (upper right), 3 (lower left), and 4 (lower right)- these s ...

Scrabble Variants
Scrabble variants are games created by changing the normal Scrabble rules or equipment. Variants with standard board and/or tiles Anagrab Anagrab is a word game which is usually played with Scrabble tiles. The name is an amalgam of the words 'anagram' (the basic game mechanism) and 'grab' - because a player's words may at any time be 'grabbed' by opponents. The game was first described in 1976 in Richard Sharp's The Best Games People Play,Sharp, Richard, The Best Games People Play London: Ward Lock Limited. but his description suggests that he did not invent it. Game play Letter tiles are placed face down and turned over one at a time. At any point (there are no turns) any player may call out a word of at least four letters. This word can be made either entirely from the pool of letters, or by adding at least one new letter to an existing word. If the new word is acceptable the person who said the word first takes the letters and places them in front of him or her. When ...

Numble
Numble is a 1968 board game published by Selchow and Righter which is very similar to Scrabble. Instead of forming words, players form sequences adhering to certain arithmetic and numerical constraints. Each tile in Numble has a single digit, 0 through 9, except for two blanks. A "word" in Numble is a string of digits in sequence (either ascending or descending). For example, 2,3,6,7 is a valid sequence (ascending), as is 7,6,3,2 (descending) while 3,6,7,1,1 (the same numbers) is not in sequence. Also, the sum of the digits must be a multiple of 3. (7+6+3+2=18, and 18 is 6 times 3.) A zero is allowed at each end and duplicate digits are allowed (except for having more than one zero at either end). The following is valid; 0,2,3,6,7,0 but not 0,0,2,3,6,7 or 2,3,6,7,0,0. 1,1,3,6,7 is okay too. Each tile is worth its digit's value in points. A blank could be placed anywhere and, unlike in Scrabble, did not count as a particular digit, so the same blank tile could, for example, be be ...

Board Game
Board games are tabletop games that typically use . These pieces are moved or placed on a pre-marked board (playing surface) and often include elements of table, card, role-playing, and miniatures games as well. Many board games feature a competition between two or more players. To show a few examples: in checkers (British English name 'draughts'), a player wins by capturing all opposing pieces, while Eurogames often end with a calculation of final scores. '' Pandemic'' is a cooperative game where players all win or lose as a team, and peg solitaire is a puzzle for one person. There are many varieties of board games. Their representation of real-life situations can range from having no inherent theme, such as checkers, to having a specific theme and narrative, such as ''Cluedo''. Rules can range from the very simple, such as in snakes and ladders; to deeply complex, as in ''Advanced Squad Leader''. Play components now often include custom figures or shaped counters, and distin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiplication
Multiplication (often denoted by the cross symbol , by the mid-line dot operator , by juxtaposition, or, on computers, by an asterisk ) is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a ''product''. The multiplication of whole numbers may be thought of as repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the ''multiplicand'', as the quantity of the other one, the ''multiplier''. Both numbers can be referred to as ''factors''. :a\times b = \underbrace_ For example, 4 multiplied by 3, often written as 3 \times 4 and spoken as "3 times 4", can be calculated by adding 3 copies of 4 together: :3 \times 4 = 4 + 4 + 4 = 12 Here, 3 (the ''multiplier'') and 4 (the ''multiplicand'') are the ''factors'', and 12 is the ''product''. One of the main properties of multiplication is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Modulo Operation
In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another (called the '' modulus'' of the operation). Given two positive numbers and , modulo (often abbreviated as ) is the remainder of the Euclidean division of by , where is the dividend and is the divisor. For example, the expression "5 mod 2" would evaluate to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0; there is nothing to subtract from 9 after multiplying 3 times 3. Although typically performed with and both being integers, many computing systems now allow other types of numeric operands. The range of values for an integer modulo operation of is 0 to inclusive ( mod 1 is always 0; is undefined, possibly resulting in a division by zero error in some programming languages).

Logarithm
In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number to the base is the exponent to which must be raised, to produce . For example, since , the ''logarithm base'' 10 of is , or . The logarithm of to ''base'' is denoted as , or without parentheses, , or even without the explicit base, , when no confusion is possible, or when the base does not matter such as in big O notation. The logarithm base is called the decimal or common logarithm and is commonly used in science and engineering. The natural logarithm has the number as its base; its use is widespread in mathematics and physics, because of its very simple derivative. The binary logarithm uses base and is frequently used in computer science. Logarithms were introduced by John Napier in 1614 as a means of simplifying calculations. They were rapidly adopted by navigators, scientists, engineers, surveyors and others to perform high-a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exponentiation
Exponentiation is a mathematical operation, written as , involving two numbers, the '' base'' and the ''exponent'' or ''power'' , and pronounced as " (raised) to the (power of) ". When is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, is the product of multiplying bases: b^n = \underbrace_. The exponent is usually shown as a superscript to the right of the base. In that case, is called "''b'' raised to the ''n''th power", "''b'' (raised) to the power of ''n''", "the ''n''th power of ''b''", "''b'' to the ''n''th power", or most briefly as "''b'' to the ''n''th". Starting from the basic fact stated above that, for any positive integer n, b^n is n occurrences of b all multiplied by each other, several other properties of exponentiation directly follow. In particular: \begin b^ & = \underbrace_ \\[1ex] & = \underbrace_ \times \underbrace_ \\[1ex] & = b^n \times b^m \end In other words, when multiplying a base raised to ...

Division (mathematics)
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication. At an elementary level the division of two natural numbers is, among other possible interpretations, the process of calculating the number of times one number is contained within another. This number of times need not be an integer. For example, if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture). The division with remainder or Euclidean division of two natural numbers provides an integer ''quotient'', which is the number of times the second number is completely contained in the first number, and a ''remainder'', which is the part of the first number that remains, when in the course of computing the quotient, no further full chunk of the size of the second number can be allocated. For example, if 21 apples are divided between 4 people, everyone receives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Addition
Addition (usually signified by the Plus and minus signs#Plus sign, plus symbol ) is one of the four basic Operation (mathematics), operations of arithmetic, the other three being subtraction, multiplication and Division (mathematics), division. The addition of two Natural number, whole numbers results in the total amount or ''summation, sum'' of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the Expression (mathematics), mathematical expression (that is, "3 ''plus'' 2 is Equality (mathematics), equal to 5"). Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects su ...

Subtraction
Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign, . For example, in the adjacent picture, there are peaches—meaning 5 peaches with 2 taken away, resulting in a total of 3 peaches. Therefore, the ''difference'' of 5 and 2 is 3; that is, . While primarily associated with natural numbers in arithmetic, subtraction can also represent removing or decreasing physical and abstract quantities using different kinds of objects including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices. Subtraction follows several important patterns. It is anticommutative, meaning that changing the order changes the sign of the answer. It is also not associative, meaning that when one subtracts more than two numbers, the order in which subtraction is performed matters. Because is the additive identity, subtraction of it does not change a number. Subtraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrebbit
Wrebbit, Inc was a puzzle-making company best known for its ''Puzz-3D'' puzzles. The company was founded in Montreal, Quebec, by Paul Gallant, and marketed itself as "The Puzzle Innovators". Its namesake appears to stem from the fact that the company's mascot is a green frog, and "Wrebbit" is either an alternative spelling or possibly a play on words of the word ''ribbit''. In the late 1990s, 3-dimensional puzzles were a successful fad, leading to a rapid growth in the company. In 2001, the business was bought by Irwin Toy. When Irwin Toy filed for bankruptcy a year later, Gallant bought back the business and relaunched it in a much reduced state. In 2005, the business was bought by Hasbro, which moved the manufacture of Wrebbit's puzzles to its facility in East Longmeadow, Massachusetts East Longmeadow is a town in Hampden County, Massachusetts, United States situated in the Pioneer Valley region of Western Massachusetts. It had a population of 16,430 at the 2020 census. East Lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
