What is the result if you subtract 15 ones from 15 tens?

Answer 1

Subtracting 15 ones from 15 tens involves converting the tens into ones to perform the subtraction. Since each ten is equivalent to 10 ones, subtracting 15 ones from 15 tens means subtracting 150 from 15, resulting in -135. This is because after converting 15 tens to ones, you have a total of 150 ones, and subtracting 15 ones leaves you with 135 ones.

Answer 2

You can't subtract 15 ones from 15 tens. The bills are all tens, so you'd have to get change first. Then you'd be subtracting 15 ones from 13 tens and 20 ones, or from 13 tens, one 5, and 15 ones.
