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
