Subtracting Integers “adding the opposite” Steps 9 – 12 keep the 1st number 9 change – to + 9 + change 2nd number to opposite 9 + (–12) follow addition rules –3 (keep, change, change) Use “Counters” & check with “Number line”.

Simplify 2 – 7 2 + (–7) – 5 (keep, change, change) Use “Counters” & check with “Number line”.

Simplify –5 – 2 –5 + (–2) – 5 (keep, change, change) Use “Counters” & check with “Number line”.

Simplify 15 – 23 15 + (–23) – 8 (keep, change, change) Try it!

Simplify –14 – (–18) –14 + 18 4 (keep, change, change) Try it!
