The act of adding two or more things together; -- opposed to subtraction or diminution.

That part of arithmetic which treats of adding numbers.

The number of persons admitted, readmitted, or transferred to a specified service during the reporting period.

Calculating a sum by adding two or more numbers.

an adding of two or more numbers to get a number called the sum Example: 5+5 = 10 10 is the sum

A mathematical operation based on "putting things together." Numbers being added are called addends; the answer is called the sum. In 12 + 33 = 45, 12 and 33 are addends, and 45 is the sum. Subtraction "undoes" addition: 12 + 33 = 45; 45 - 12 = 33, and 45 - 33 = 12.

the arithmetic operation of summing; calculating the sum of two or more numbers; "the summation of four and three gives seven"; "four plus three equals seven"

The sum of two numbers a and b, where a and b are the addends.

The operation of increasing one number by a certain amount to get a sum.

Addition is the mathematical operation of combining two or more numbers into a sum.

The process of combining two or more numbers to find their sum. Addition is used to find the result of putting together items in a group, or parts in a whole. Addition is indicated by the plus sign (+). Addition is the opposite of subtraction.

each real number has an additive inverse, denoted –, such that their sum is 0.  For example –3 is the inverse of 3 because –3 + 3 = 0.

Addition is the summing of numbers to determine their total.

The operation, or process, of calculating the sum of two numbers or quantities.

Addition is the mathematical operation of increasing one amount by another. The result of adding two quantities a and b is their sum, a + b; it is a more than b, and b more than a. For example, 3 + 2 = 5 \!\ , since 5 is 2 more than 3.
