1  2a,3a,4a

2  2a,x

   4ab+6y, 7x-y

     ab-y-2x, a+2x+z

3 ( 12m^-4m^)+(-9m-7m)+10

8m^-16m+10

4  ( 30ab+12b+14a )-(24ab-10b-18)

30ab+12b+14a-24ab+10b+18

(30ab-24ab)+(12b+10b)+14a+18

6ab+22b+14a+18

5   5m/2-4

5.2/2-4

10/2-4

5-4=1

6    3(2x-1)+3x+11

3(10-1)+15+11

3(9)+26

27+26

53

7    z3-3(z3-10)

1728-3(1728-10)

1725.1718

2980790

8    ( x+y )+15

      (x+y)+(xy)
