If \( 604 - 72 = \_\_\_ \), then \( 532 + \_\_\_ = 604 \).

Explain the process of checking your work.

First we have to subtract 72 from 604. But we can do it into two steps. Then it makes much easier. 604-72=600+4-70-2=600 +2-70=530+2=532
And now we want to obtain 604 again. But before we calculate it, think what we already did. We subtract 72 from 604 and our result was 532. Now we want back to 604 again, so we have to add 72 to 532. In few steps to do it easier. 532+72= 530 + 2+ 70 + 2= 600 + 4=604

the answer is 72 because 604-72=532 and 532+72=604

To determine the missing numbers, we subtract 72 from 604 to find that it equals 532. Then, by adding 532 and the missing number (72), we confirm that it equals 604. Both steps validate our solution and confirm the correctness of the calculations.
