Answer 1

Step-by-step explanation:

a.4+2-3+5

6-3+5

3+5

=8

b.15-3-2×2

=54

d.69+4-11×6-3

69+4-66-3

73-66-3

7-3

=4

e. 40×6+(9+21)

40×6+(30)

240+30

=270

f.15-3×12+(3+1)

15-3×12+4

15-36+4

-21+4

=-17

g.(17-6+2)×(12+11)

(11+2)×(12+11)

13×(12+11)

13×23

=299

h.[(18+15)-3]-2×5

[33-3]-2×5

30-2×5

30-10

=20

i.3[(19-15+3)+(4-2)]

3[(4+3)+(4-2)]

3[(7)+(4-2)]

3[(7)+(2)]

3×9

=27
