The operation used to find the sum of integers is addition.
When you add integers, you are combining their values to find a total. The rules for adding integers depend on whether they have the same sign or different signs.
-
Integers with the Same Sign: If you are adding two integers with the same sign (both positive or both negative), you add their absolute values and keep the same sign. For example:
- 3 + 5 = 8
- (-3) + (-5) = -8
-
Integers with Different Signs: If you are adding two integers with different signs (one positive and one negative), you subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value. For example:
- (-7) + 4 = -3 (Because |-7| > |4| and -7 is negative)
- 7 + (-4) = 3 (Because |7| > |-4| and 7 is positive)
Subtraction, multiplication, and division perform different functions and will not directly give you the sum of integers. While subtraction can be represented as adding a negative integer, the fundamental operation for finding the sum is addition.
