Take the following mathematical statement:

1 _ 5 _ 1 _ 5 = 3

Your job is to fill in the blanks in such a way that this statement will be true. The blanks could logically be filled with any symbol associated with math and/or numbers, as long as they make a true statement in the end. Good luck, everyone.

Edit: thread title was supposed to continue, "...though the answer's so simple."

Yes, all standard rules of mathematics will apply here, so assume multiplication and division is done first.

Yes, all blanks have to be filled.

Also, remember, the blanks are not limited to simply +, -, /, or X. ANY item associated with math and/or numbers can be used.

Yeah you got it right, and made me feel like an idiot in the process. (I wasn't able to figure it out when it was shown to me.) 😛
