Question

Using 0-9, what 4 numbers equal 25?

Answer 1

`9,6,3,` and `7`

Explanation:

This question is considered "guess and check". You would have to take a guess at what the answer is and then double check it. There is no formula to solve it in one go.

To begin, we want to try to think of some numbers that we could add together to equal about `1/2` of `25` or something close to half. At this point, I tried to get `15` and `10` so that I could add them together and get `25`.

I began by adding `9` and `6` together and got `15`. After this, I added `3` and `7` together to get `10` since we already used `6` and couldn't use `5`.

This gives you the answer of `25`.

I hope this helped!
