right in here your potential answers where you're going Interesting
- 00:23
question All right well so they're a couple of ways
- 00:25
we could go about solving this one One way would
- 00:29
be to just put these four numbers in a different
- 00:31
combinations and see which ones matched the answer Joyce well
- 00:35
yeah so for example three times five fifteen and two

- 01:09
