Brush up your maths: answer to BODMAS exercise

Calculate the following: (9 + 1) × (5 – 2) + 8/2 – 3

First we evaluate the brackets:

(9 + 1) × (5 – 2) + 8/2 – 3 = 10 × 3 + 8/2 – 3

Then we divide:

10 × 3 + 8/2 – 3 = 10 × 3 + 4 – 3

Next we multiply:

10 × 3 + 4 – 3 = 30 + 4 – 3

Next we add:

30 + 4 – 3 = 34 – 3

Finally, we subtract:

34 – 3 = 31
