1.	Subtract the following. (i) + 32 – (+12) (ii) + 7 – (+15) (iii) (-14) – (-20) (iv) (-30) – (-15) (v) 23 – (-10) (vi) (-27) – 22
Answer» (i) + 32 – (+12) = 32 – 12 = 20 (ii) + 7 – (+15) = 7 – 15 = – 8 (iii) (-14) – (-20) = – 14 + 20 = 20 – 14 = 6 (iv) (-30) – (-15) = – 30 + 15 = 15 – 30 = – 15 (v) 23 – (-10) = 23 + 10 = 33 (vi) (-27) – 22 = – 27 – 22 = – 49

Subtract the following. (i) + 32 – (+12) (ii) + 7 – (+15) (iii) (-14) – (-20) (iv) (-30) – (-15) (v) 23 – (-10) (vi) (-27) – 22

Answer»

(i) + 32 – (+12) = 32 – 12 = 20

(ii) + 7 – (+15) = 7 – 15 = – 8

(iii) (-14) – (-20) = – 14 + 20 = 20 – 14 = 6

(iv) (-30) – (-15) = – 30 + 15 = 15 – 30 = – 15

(v) 23 – (-10) = 23 + 10 = 33

(vi) (-27) – 22 = – 27 – 22 = – 49
