Question

B) 315:9 - ( 8 + 5 x 20) :12 - 5 x 5=

c) 18 x 14 : 6 - (63 : 7 + 1) x 2 x 2=

D (4 + 7 x 4) : 4 x 2 + 15 . 7 - 11 x 11=

Answer 1

B) 315 : 9= 35
(8 +5 X 20) = 108
108 :12=9
9-5 X 5= 16.

C) 18 X 14 =252
252 : 6 =42
(63:7+1)= 10
10 X 2 X 2 =40.

D) (4.X 7.X 4)=112
112: 4 X 2 + 15 =71
71 X 7 -11 X 11 = 376
