(iv) − 28 by 14
(v) − 53 by 18
(vi) − 35 by 0
(vii) 0 by − 23
(viii) − 16 by − 12
(ix) − 105 by − 8
(x) − 36 by − 50
(xi) − 28 by − 1
(xii) 25 by − 11

Answer 1

(i) 16 $\times$ 9 = 144
(ii) 18 $\times$ (−6) = $-(18\times 6)=$−108
(iii) 36 $\times$ (−11) = $-(36\times 11)=$−396
(iv) (−28) $\times$14 = $-(28\times 14)=$−392
(v) (−53) $\times$ 18 = $-(53\times 18)=$−954
(vi) (−35) $\times$ 0 = 0
(vii) 0 $\times$ (−23) = 0
(viii) (−16) $\times$ (−12) = 192
(ix) (−105) $\times$ (−8) = 840
(x) (−36) $\times$ (−50) = 1800
(xi) (−28) $\times$ (−1) = 28
(xii) 25 $\times$ (−11) = $-(25\times 11)=$−275
