Adding Integers
Integers with the Same Sign
Adding integers that have the same sign is pretty straightforward. Add the two numbers together
and maintain the sign.
Example: 200+500=700
Both numbers are positive so we add the numbers together and number remains positive.
Both numbers are positive so we add the numbers together and number remains positive.
Example: -- 300 + (-- 900) = -- 1,200
Both addends are negative, so we add them together and maintain the negative sign.
Integers with Different Signs
When adding integers with different signs, ignore the signs at first and subtract the smaller number
from the larger. The final sum will maintain the sign of the larger addend.
