D)-21÷(-2-5)+(-14)+6×(8-4×3)=​

Answer 1

A)40÷20-3×5+8÷4+1=

2 - 15 + 2 + 1 =

- 13 + 3 = - 10

B)3-14÷7-5×4-9÷3×4=

3 - 2 - 20 - 3 x 4 =

3 - 2 - 20 - 12 =

1 - 32 = - 31

C)5×(-7+3)-12÷(-4)+20÷(1-6)=

- 35 + 15 + 3 + 20 ÷ (-5) =

- 35 + 15 + 3 - 4 =

- 20 - 1 = - 21

D)-21÷(-2-5)+(-14)+6×(8-4×3)=

- 21 ÷ (-7) - 14 + 6 x (8 - 12) =

3 - 14 + 48 - 72 =

- 11 + 48 - 72 =

37 - 72 = - 35
