Adding Integers
ex.
(+5) + (-2) = ?
How to add Integers:
1. Add these to help you out:
+5 = have 5
-2 = owe 2
2. +5 = +++++
-2 = --
*The rest is 3 +'s. So the answer is +3
(+5) + (-2) = +3
ex.
(+6) + (-4) = +2
have 6 & owe 4 = have 2
++++++
- - - -
Subtracting Integers
ex.
5 - 2 = +3
have 5 remove owe 2 = have 3
so it becomes..
5(-2) = +3
then use +s & -s
5(-2) = +3
+++++
--
