1) ab 32 | -49 | 32 | 0 | -7.2 |

     8   | -1   | 0.5 | 0 | -0.2| -2

2) a) -2.88 - 0.72 = - 3.6    

    b) - 7.8 - 22.2 = - 30

3) -3x + 6 = - 15

-3x = - 15 - 6

-3x = - 21

x = - 21 / (- 3)

x = 7

4) a) 10pq * (- 0.0.10) r = - 0.1pqr

    b) - 10st * (- 0.1q) = stq

5) ( - ) * = ( - ) * 16 = * 16 = 62

6) = -x

x = -

x = - ÷ = - *

x = - = - 12
