Find the sum of the pairs of integers: (a) – 6, – 4 (b) +3, – 4 (c) +4, –2

Answer»

(a) – 6 and – 4 both have negative signs.

So, – 6 + (– 4) = – (6 + 4) = –10

(b) + 3 and – 4 have opposite signs.

As 4 – 3 = 1, therefore + 3 + (– 4) = –1

(c) + 4 and –2 have opposite signs.

So, 4 + (–2) = 4 – 2 = 2
