Subject: Combinations of numbers/operators?

This is a really easy one but I'm kind of a kook and new to programming
so any help is appreciated.

Let's say I have an array consisting of 4 integers i.e. 1,2,3,4. I would
like to print every combination of these numbers using math operators
such as +-/*. The output should resemble something like:

1+2+3+4 = 10
1+2+3-4 = 2
1+2-3-4 = -4
....

This seems pretty straightforward and should only take a couple lines of
code (nested loops?) but I can't quite figure out. Anyone?

Thank you.
