-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
Subtracting an integer is the same as adding the additive inverse. In symbols: a - b = a + (-b), where "-b" is the additive inverse (the opposite) of b.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
if the signs are the same you must add its opposite.
adding and subtracting integers is when you add and minus 2 numbers
Some do, some don't. The operations are equivalent and people do what they are more comfortable with.

When adding negative integers, you subtract. (2+-1=1) When subtracting negative integers, you add. (2--3=5)
what are some examples of subtracting integers

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
to subtract an integer, add its opposite or additive inverse.
