Worksheet Overview

Written multiplication can be done step-by-step by setting out the calculation carefully and remembering to carry numbers if necessary.



Work out:


947 × 7



Rewrite the calculation vertically, like this:


947 x 7

Multiply the numbers in the ones column together, so 7 × 7 = 49

Write the 9 in the ones column and carry the 4 tens below to the doorstep of the tens column.


947 x 7 ones


Next, multiply the numbers in the tens column together, so 4 × 7 = 28 and add the 4 tens that were on the doorstep.


947 x 7 tens


This gives us 28 + 4 = 32 , so we write the 2 in the tens column and carry the 3 hundreds below on to the doorstep of the hundreds column.


947 x 7 hundreds


Lastly, multiply the numbers in the hundreds column, so 9 × 7 = 63 and add the 3 that was on the doorstep.

This gives us 63 + 3 = 66 in the thousands.


947 x 7 thousands


So, in full, we have:

947 x 7 answer


So      947 × 7 = 6,629
