Add & Subtract Integers • 1) pos + pos= pos 10 + 5= 12 +27= 2) Neg + neg= neg -10 + (-5)= -7 + (-4)- 3) Neg – Neg = BIGGER Negative number -12 -4 = -6 – 15 = 4) Pos + Neg= find the difference between the numbers & the bigger sign wins** -15 + 7 = -5 + 25 = 5)Neg – (-Neg) = Kill the Bad Guy 12 – (-4) = - 8 – (-9) =
Practice: • 1) -12 + 4 • 2) -6- 6 • 3) -13 + (-10) • 4) -8 - 19
