There are some rules
that I have learned that
I want to share with you.
Rule 1:
if they have the SAME SIGNs...
ADD the numbers together and KEEP the sign. For Example:

2 + 5 = 7
Simple I know.

This of course makes
sense, ADD 5 + 2 = 7
And KEEP the Positive. Or for Example:

-2 + (-5) = -7

Remember...The rule says if the signs are the SAME, "ADD and KEEP".

So ADD 2 + 5 = 7, and then KEEP the negative sign to make it -7. Okay, So you want some
video. Here you go. Rule 2:
SUBTRACT the numbers and KEEP the sign of the larger "number". For Example:

7 + (-10) = -3

So if there are DIFFERENT SIGNS....
SUBTRACT the numbers 10 - 7 = 3,
then KEEP the sign of the larger "Number"
So we KEEP the NEGATIVE sign to get -3
Now its time to get in some practice! Adding Integers 10 > 7 Now Let's Hear a BULLDOG VERSION!!! SAME signs ADD and KEEP

DIFFERENT signs SUBTRACT

KEEP the sign of the HIGHER NUMBER,

Then it'll be EXACT
