Use one straight line, horizontal, vertical or diagonal to make this statement valid:

5 + 5 + 5 = 550

I rule out the obvious one: a diagonal strike across the '=' changes the equation showing that the sides are not equal which of course is valid.

There are at least 3 other possible solutions I know of.

You have 3???? I can't even come up with one tsk tsk

Ok, here is what I got

1) change the first + to 4:

545+5=550

2) change the second + to 4

5+545=550

3) change the = to "less than or equal to" sign

and you already ruled out the last one, do you have more solutions?

I did not rule that one out. I ruled out the "not equal" which I unfortunately can't type using the keyboard only. I am so used to mathematical editors ;)

Congratulations Tanny!

Gee Whiz...I'm gonna have to take in my daily dose of caffeine and come back here a little later...like maybe when my brilliant son gets up! lol!!

Put a diagnal line through the = and it means NOT equal
