Question

125x11 while using brackets

Answer 1

125×11=1375

Grid method

You can use a grid method to expand brackets. In this example you can expand 10(5t + 6) using a grid.

Down the left-hand side, put the number outside the brackets. ...

Then fill in the spaces by multiplying each term separately.

With this example, you can work out that:

10(5t + 6) = 50t + 60.
