Insert one set of parenthesis to make this equation true:7 + 3 X 2 + 5 X 4 = 73My daughter had this on a test today. She can easily make it 72, but we don't see how 73 is possible.

Just start going through the possibilities:
First: A paren before the 7 and close it at either the 3 or 2. You don't need to try the close it at the 5 becaue that would make it even.
Second: A paren before the 3 and close it at the 5 or 4 since closing it at the 2 was done last time.
...




















Actually, I would start by putting a paren before the two and trying out the 5 and then the 4 or, if I were smarter, maybe at the 4 and then

Just so that you know - it is possible to get 73

Hi, I must say that I take offense regarding you comment regarding Ishuda reply. I would love to know why you think Ishuda or anyone else should answer your question? is it that you are special? This is a help forum, not a we will do your homework forum or answer all your math questions forum. I advise you to do a google search for a private tutor if you want that type of service.
Instead of spending the time insulting Ishuda excellent instructions on how to solve the problem maybe you could have instead spent the time trying what he suggested.
