Subtracting Integer Rules

10/29/2014

Hi there, I'm going to tell you three rules of Subtracting Integers.

Rule 1: Simple Subtraction. example---> 90 - 1 = 89
Rule 2: Make it addition. example---> -8 - (9) = -17 to: (taking away the minus and putting it in the 9 to make it -9 so -8 -9 and just add the + sign in the middle.
Rule 3: Fix the Stix. example---> 5 - (-7) ( Fix the Stix meaning fix the two lines making it an addition sign 5 + 7 = 12

These are the rules to doing Subtraction Integer courses and these can help you doing tests and other things that get you stuck on. And here is My Video from smart

Hey dere, I thought the way you worded it was fine, but you were really quiet and I couldn't really hear you. overall you should work on speaking louder but it was good.
