Question

Unbundle a hundred to make enough tens 603 -239 ____

Answer 1

In order to calculate this subtraction, first let's use one unit from the hundreds to create 10 tens.

Then, we will need one unit from the tens to make 10 more units.

So the first number in the subtraction will be 5 hundreds, 9 tens and 13 units.

We will have the following subtraction:

$\begin{gathered} \text{units:} \\ 13-9=4 \\ \text{tens:} \\ 9-3=6 \\ \text{hundreds:} \\ 5-2=3 \end{gathered}$

So the final result is 364.
