Question

. d. (7 * 3-9) x 2 - 64:08:4+ 36:6) e. (36 - 4x 9 x 0)* 4-12 x 12 f. 2x (28-81:9 x 3) +2:06*7-5* ​

Answer 1

d) (7 x 3-9) x 2 - 64 : (8 : 4 + 36:6)=

= (21-9) x 2 - 64 : (2+6) = 12 x 2 - 64:8 = 24-8 = 16

e) (36 - 4x 9 x 0) x 4-12 x 12 =

= (36-0) x 4 - 144 = 36 x 4 - 144 = 144-144 = 0

f) 2 x (28-81:9 x 3) +2 : (06 x 7-5 x 8)=

=2 x ( 28-27) + 2 : (42-40) = 2 x 1 + 2:2 = 2+1 = 3
