Addition & Subtraction
Same Signs ADD & KEEP
Add numerical values. Keep their original sign.
5 + 3 = 8 (-5) + (-3) = -8
Diff Signs SUB & DOMINATE
Subtract small from big. Keep sign of larger magnitude.
(-7) + 12 = 5 7 + (-12) = -5
Subtraction: K-C-C
Keep 1st, Change subtraction to addition, Change 2nd sign.
Multiplication & Division
Same Signs ALWAYS (+)
If signs match, result is positive.
4 × 3 = 12 (-4) × (-3) = 12
Different Signs ALWAYS (-)
If signs don't match, result is negative.
4 × (-3) = -12 (-12) ÷ 3 = -4
Guided Sandbox Work step-by-step with your teacher!
