Addition of IntegersRules for Adding & Subtracting Integers 1 + & - becomes - (2+(-3)=2-3-4-(+8)=-4-8) 2 + & + becomes + (5+(+1)=5+1 -7+(+3)=-7+3) 3 - & - becomes + (4-(-6)=4+6-9-(-2)=-9+2)Let’s look at some examples (1) 2 + (−3) = 2 Taking − common = −(−2 + 3) = −(3 − 2) = −1 (2) −4 + (+8) = −4 Writing bigger number first = 8 – 4 = 4 Rough + & − becomes − + & + becomes + − & − becomes + (3) 5 + (+1) = 5 = 6 (4) −7 + (+3) = −7 Taking − common = −(7 − 3) = − 4 (5) 4 + (−6) = 4 Taking − common = −(−4 + 6) Rough + & − becomes − + & + becomes + − & − becomes + = −(6 − 4) = −2 (6) −9 + (−2) = −9 Taking − common = −(9 + 2) = −11 Rough + & − becomes − + & + becomes + − & − becomes +
