Question

What is `72 -: 4`?

Answer 1

`18`

Explanation:

First set up the equation as a long division problem:

Ask yourself, "How many times can `4` go into `7`?" The answer is 1 time. Subtract `4` from `7` to get `3`.

Bring down the `2` and ask yourself the question again. "How many times can `4` go into `32`?"
The answer is `8` times. Subtract `32` from `32` to get a remainder of `0`. The final answer is `18`.
