Fill in the missing number.

Here we see an example of someone multiplying 184 by 76. This is an example of multiplying a three-digit number by a two-digit number. And when we multiply something by a two-digit number, this spot is filled in by what we call a placeholder. We have to hold this space open. It is empty.

What number do we usually use to represent empty or a placeholder? Zero. The missing number from this position is a zero. Now that we know what goes in this position, we can complete the calculation. We can add.

To complete the calculation, we’ll add 1104 to 12880. Starting all the way on the right, four plus zero is four. Eight plus zero is eight. One plus eight is nine. One plus two is three. One plus zero is one. The completed calculation is 13984.
