Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

It is commonly abbreviated as m (not to be confused with the metric prefix for 1×10−3) or M and MM ("thousand thousands", from Latin "Mille"; not to be confused with the Roman numeral MM = 2,000), mm, or mn in financial contexts. In scientific notation, it is written as 1×106 or 106.

A chemical symbol is a one- or two-letter designation of an element. Compounds are combinations of two or more elements. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Many elements have symbols that derive from the Latin name for the element.

A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8. ... If a term has more than one variable, the degree is equal to the sum of the exponents of all its variables.

In exponential notation, a is termed the base while n is termed the power or exponent or index. Scientific notation is a specific example of exponential numbers, 10 is almost always used as the base number. Thus 103 means 10×10×10, while 10-3 is the notation for the reciprocal of 103 namely 1/1000.

Definition 1: The number that gets multiplied when using an exponent. Examples: • in 82, 8 is the base, and the result is 8 × 8 = 64. • in 53, 5 is the base, and the result is 5 × 5 × 5 = 125. Definition 2: How many digits in a number system.

In computer programming, ellipsis notation (.. or ...) is used to denote ranges, an unspecified number of arguments, or a parent directory. Most programming languages require the ellipsis to be written as a series of periods; a single (Unicode) ellipsis character cannot be used.

Scientific notation (also referred to as scientific form or standard index form, or standard form in the UK) is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. ... Standard notation is the normal way of writing numbers.

Physicists and chemists use a standard notation to indicate the electron configurations of atoms and molecules. For atoms, the notation consists of a sequence of atomic subshell labels (e.g. for phosphorus the sequence 1s, 2s, 2p, 3s, 3p) with the number of electrons assigned to each subshell placed as a superscript.

Big O Notation is a relative representation of an algorithm's complexity. ... It is the relative representation of the complexity of an algorithm. It describes how an algorithm performs and scales. It describes the upper bound of the growth rate of a function and could be thought of the worst case scenario.

Exponents. Exponents, or powers, are a way of indicating that a quantity is to be multiplied by itself some number of times. In the expression 25, 2 is called the base and 5 is called the exponent, or power. 25 is shorthand for "multiply five twos together": 25 = 2×2×2×2×2 = 32.

Last modified March 22, 2009. Prism switches to scientific notation when the values are very larger or very small. For example: 2.3e-5, means 2.3 times ten to the minus five power, or 0.000023. 4.5e6 means 4.5 times ten to the sixth power, or 4500000 which is the same as 4,500,000.
