EXAMPLES

–       2 + 5 x 3 = 2 + 15 + 17

–       30 / 5 x 3 = 6 x 3 = 18

–       6 x (5 + 3) = 6 x 8 = 48

Have a go at completing the following… ensure you solve the operations in the correct order.

1. 7 + (6 x 7) =

2. 3 x (20 + 10) =

3. 2 + 4 x 4 + 3 =

4. (4 + 5) x (14 – 8) =

5. 15 – (3 x 4) =

6. (17 + 3) + (20 – 11) + (9 x 7) =

7. 8 x (5 x 2) + (12 x 5) =

8. 4 x (17 – 12) – (3×15) =
