Long and short scalesThe long and short scales are two powers-of-ten number-naming systems that are consistent with each other for smaller numbers, but are distinct for larger numbers. Much of the world has adopted either the short or long scale. Countries using the long scale include most countries in continental Europe and most that are French-speaking, German-speaking and Spanish-speaking.
Order of magnitudeIn a ratio scale based on powers of ten, the order of magnitude is a measure of the nearness of two figures. Two numbers are "within an order of magnitude" of each other if the ratio of the greater to the lesser is between 1 and 10. In other words, the two numbers are within about a factor of 10 of each other. For example, 1 and 1.02 are within an order of magnitude, as well as 1 and 2, 1 and 9, and 1 and 0.2.Names of large numbersDepending on context (e.g., language, culture, region), some large numbers have names that allow for describing large quantities in a textual, not mathematical, form. For very large values, the text is generally shorter than a decimal numeric representation, although longer than scientific notation. Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales.
Orders of magnitude (numbers)The logarithmic scale can compactly represent the relationships between variously sized numbers.This list contains selected positive numbers in increasing order of magnitude, including counts of things, dimensionless quantities, and probabilities. Each number is given a name in the short scale, which is used in English-speaking countries, as well as a name in the long scale, which is used in some of the countries that do not have English as their national language.

ExponentiationArithmetic operationGraphs of y = b for various bases b. Each curve passes through the point (0, 1) because any nonzero number raised to the power of 0 is 1.
IntegerAn integer is the number zero (0), a positive natural number (1, 2, 3, ...), or the negation of a positive natural number (−1, −2, −3, ...). The negations or additive inverses of the positive natural numbers are referred to as negative integers.
MathematicsMathematics is a field of knowledge concerned with abstract concepts such as numbers, geometric shapes, sets, functions, and probabilities. It uses logical reasoning and proof to study and establish their properties, often expressed as theorems, formulas, and equations. Mathematics is used to model and solve problems in science, engineering, technology, economics, and everyday life.MultiplicationArithmetical operationFour bags with three marbles per bag gives twelve marbles (4 × 3 = 12).Multiplication can also be thought of as scaling. Here, 2 is being multiplied by 3 using scaling, giving 6 as a result.Multiplication 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.
Scientific notationScientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form, since to do so would require writing out an inconveniently long string of digits. It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations.1010 (ten) is the natural number following 9 and preceding 11. Ten is the base of decimal numeral systems, the most common systems for denoting numbers in both spoken and written language. The English name for the number "ten" originates from the Proto-Germanic root *tehun, which in turn comes from the Proto-Indo-European root *déḱm̥. This root is the source of similar words for "ten" in many other Germanic languages.*As an Amazon Associate I earn from qualifying purchases.
