Question

Evaluate :
(1) (-20) + (8) ÷ (-2) x 3
(2) 16 + 8 ÷ 4 - 2x 3
(3) 27 - [5 + {28 - (29 - 7)}]
(4) -8 -{-6 (9 - 11) + 18 ÷ -3}​

Answer 1

Answer:

1)(-20)+(8)÷(-2)×3

=(-20)+(-4)×3

=(-20)+(-12)

=(-32)

2)16+8÷4-2×3

=16+2-6

=18-6

=12

3)27-(5+(28-(29-7)

=22+(28-(29-7)

=50-(29-7)

=21-7

=14

4)-8-6(-6 (9-11)+18÷3

= -8-6(-6(9-11)+6

= 14-6×9-11)+6

=8×9-11+6

=72-11+6

=61+6

=67

Hope its will help u
