Algorithm

a step-by-step solution to a problem;

A logical step-by-step procedure for solving a mathematical problem in a finite number of steps, often involving repetition of the same basic operation.

Absolute value

The distance from a point on the number line to zero; the absolute value is always positive.

Algebraic expression

An expression made up of three things: numbers, variables, and math operations; terms combined by an operation that has variables and numbers.

2a has a number, variable, and multiplication

a+b has two variables, and addition

2a has a number, variable, and multiplication

a+b has two variables, and addition

Composite number

A number that can be divided evenly by numbers other than 1 or itself.

Prime number

A whole number that is divisible by only 1 & itself.

Division

splitting into equal parts or groups. It is the result of "fair sharing".

Divisor

The number you divide by.

dividend ÷ divisor = quotient in 12 ÷ 3 =4, 3 is the divisor

dividend ÷ divisor = quotient in 12 ÷ 3 =4, 3 is the divisor

Dividend

The amount that you want to divide up; dividend ÷ divisor = quotient

Example: in 12 ÷ 3 = 4, 12 is the dividend.

Example: in 12 ÷ 3 = 4, 12 is the dividend.

Product

The answer to a multiplication problem. Example 2 and 3 is 6. 6 is the answer to the multiplication problem.

Factor

when whole numbers other than zero are multiplied together, each number is a factor of the product. 5 & 2 are factors of 10

Equivalent

The state of being equal. Having the same amount or value.

Example: 60 seconds = 1 minute

Example: 60 seconds = 1 minute

Fraction

Part of a whole; a number written with the bottom part (the denominator) telling you how many parts the whole is divided into, and the top part (the numerator) telling how many you have.

quotient

from quot-, "how many". The result of a division problem. 63 ÷ 9 = 7

place value

The value of where the digit is in the number, such as units, tens, hundreds, etc.

estimate

It is when you give a value that is closest to the original value.

polygon

A closed plane figure that is formed by three or more segments called sides. Each side intersects exactly two other sides at a vertex.

relatively prime

When the common factor for any two numbers is 1; an example is when I am simplifying fractions.

GCF

The largest factor shared by a set of numbers.

equivalent fractions

Fractions that have the same value but different numerators & denominators.

multiple

The product of a whole number and any nonzero whole numbe. Example: ________ of 4: 4, 8, 12, 16, 20, 24, 28...

LCM

This is the smallest common multiple of two or more nonzero whole numbers.

mixed number

A number that is made up of a whole number and a fractional part.

improper fraction

A fraction whose numerator is larger than or equal to the denominator.

terminating decimal

A decimal that ends. Example, 0.4

repeating decimal

A decimal whose numeral goes on forever. Example, 0.3333333333333333333......
