Answer 2

It looks like you've provided a mathematical expression: 57:89+(76:5)•87-70. However, the notation you've used (with colons and parentheses) is not standard mathematical notation, so I'm not entirely sure how to interpret it. Could you please clarify the notation you're using? Specifically, what do the colons (:) represent, and are the parentheses used for grouping or multiplication?

If you can provide the expression using more standard mathematical symbols and notation, I'd be happy to help you solve it.
