Glossary and Terms: Operations

Addends - The numbers that are added together in addition problems.

Example: 5 + 3 = 8, the addends are 5 and 3

Addition - The mathematical operation where two or more numbers are combined to make a sum. The "+" sign is used to indication addition.

Example: 4 + 2 + 7 = 13

Common factor - A factor that is shared by two or more numbers.

Example: The numbers 12 and 9 share the common factors 1 and 3. The number 4 is a factor of 12, but not 9 so it is not a common factor.

Dividend - When dividing, the dividend is the number that is getting divided or broken up.

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

Divisible - A number is divisible if it can be divided without leaving a remainder.

Example: 12 ÷ 4 = 3. In this case, 12 is divisible by 4.

Division - A mathematical operation where a number is split into equal groups.

Example: 12 ÷ 4 = 3. In this example 12 is split into 4 equal parts of 3.

Divisor - In division, the divisor is the number by which the dividend is divided.

Example: 12 ÷ 4 = 3. In this example the 4 is the divisor.

Factors - The numbers that are multiplied together to get an answer in a multiplication operation.

Example: 4 x 6 = 24, the numbers 4 and 6 are factors.

Greatest common factor - The largest number that is a common factor of two numbers.

Example: The numbers 12 and 9 share the common factors 1 and 3. The number 3 is the greatest common factor.

Minuend - In a subtraction operation, the minuend is the number from which another number is subtracted.

Example: 40 - 10 = 30, in this operation 40 is the minuend.

Multiple - A multiple is the product of any number and another whole number.

Example: 3, 6, 9, 12, and 15 are all multiples of 3

Multiplication - The mathematical operation of scaling one number by another. It can be thought of as adding the same number together a given number of times. The symbol "x" is often used to indicate a multiplication operation.

Example: 5 x 3 = 15, this can also be written as 5 + 5 + 5 = 15.

Product - The product is the answer to a multiplication operation.

Example: 5 x 3 = 15, in this example 15 is the product.

Quotient - The quotient is the answer to a division operation. The quotient does not include the remainder, if there is one.

Example: 12 ÷ 4 = 3. In this operation, 3 is the quotient.

Remainder - The remainder is the amount left over after a division operation.

Example: 22 ÷ 4 = 5 r 2. In this example the remainder is 2.

Square - An operation where a number is multiplied by itself. It is written with a small 2 to the right of the number like X2.

Example: 52 = 5 x 5 = 25

Square root - A number that produces a given number when multiplied by itself. The symbol for square root is √.

Example: √ 25 = 5, 5 is the square root of 25 because 5 x 5 = 25.

Subtraction - A mathematical operation that solves for the difference between two numbers. The symbol for the operation is "-", which is also called the "minus" sign.

Example: 8 - 2 = 6

Subtrahend - This is the number that is subtracted in a subtraction operation.

Example: 8 - 2 = 6, in this example 2 is the subtrahend.

Sum - The answer to an addition operation.

Example: 8 + 7 = 15, in this example 15 is the sum.
