Subtract and then check by adding: $93 - 58 .$

How did it go?

Write the numbers so each place value lines up vertically.
Subtract the ones. We cannot subtract 6 from 3, so we borrow 1 ten. This makes 3 tens and 13 ones. We write these numbers above each place and cross out the original digits.
Now we can subtract the ones. $13 - 6 = 7.$ We write the 7 in the ones place in the difference.
Now we subtract the tens. $3 - 2 = 1.$ We write the 1 in the tens place in the difference.
Check by adding. Our answer is correct.
