Question
Find the sum of $(– 9) + (+ 4) + (– 6) + (+ 3)$
✓
Answer
We shall re-arrange the numbers, So that the positive integers and the negative integers are grouped together. So, We have
$(– 9) + (+ 4) + (– 6) + (+ 3) = (– 9) + (– 6) + (+ 4) + (+ 3) = (– 15) + (+ 7) = – 8$
$(– 9) + (+ 4) + (– 6) + (+ 3) = (– 9) + (– 6) + (+ 4) + (+ 3) = (– 15) + (+ 7) = – 8$
