Re: operations puzzles

You do not say, but can the numbers be rearranged in any order? Can you insert grouping symbols?

Re: operations puzzles

Plus are you SURE you typed the problem correctly;
the 4th number being 50, plus result equal 50, sure looks fishy to me...

Must the order you typed be maintained?
You can have 10 / 5 - 2 + 50 = 50, or 10 / 2 - 5 + 50 = 50, but that starts with the division...
