Use bodmas and the rules required for addition, substraction and multiplication of integers

1. a=2 b=3

ii) 2*2+2*3

=4+6

=10

vi)2*2*2-3*3*3

=8-27

=-19

2)v) 2*1*1*2-5*2*5+1*2*2

=4-50+4

=4-54

= -50

3) ii)2*(-2*-2)-(-1*-1)+3*(3*3)

=2*4-1+3*9

=8-1+27

=7+27

=34

iv)(-2*-2*-2)+(-1*-1*-1)+(3*3*3)+3*-2*-1*3

= -8+ -1+27+18

= -9+45

=36
