Write the two missing numbers to make this long multiplication correct.

We know that we have to multiply these two two-digit numbers together to total 1066. We just don’t know what these two missing digits are. We do know that forty something multiplied by six is 246. We can find the missing number by dividing 246 by six. There are no sixes in two. There are four sixes in 24. And six divided by six is one. So 246 divided by six is 41. So we know that 41 multiplied by six is 246.

Now we just need to work out the missing number in the tens column. What do we multiply 41 by to give us 820? We know that 41 multiplied by two is 82. So 41 multiplied by 20 is 820. So the missing digit is a two, which represents two tens or 20. So the two missing numbers are one and two. 41 multiplied by 26 equals 1066.
