Simple Addition
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.

Add ONE STRAIGHT LINE to the above to make the sum correct.
Answer
5 4 5 + 5 = 550
Add a straight line to the first "+" to make it a "4".

| or you could just draw a line through the '=' to make it 'not equals' (cop out answer, i know) |

| This Teaser worked the proper way on my mind, at the time. I failed to really look at the equation and started to concoct fancy ways of figuring out this simple and very simple addition problem.
Good Work. |

| Good Teaser! Clever - I'm going to show that one to my grandchildren. I finally found one I won't have to call Auntiesis and have her explain to me.

| This teaser was challenging in the process, but once you finally click on the answer it's like ohhhhhh! At first I didn't understand the question... maybe that should be corrected... |

| ALTERNATE ANSWER: Place the single straight line as a left slant directly over the equals sign to form the inequality: 5 + 5 + 5 "is less than" 550 (I cannot insert the symbol correctly in this comment) |

| I also added a slanted straight line through the = sign to mean "not equal to" - good teaser.  |

| Haha I added the line through "=" because 5+5+5 "is not equal to" 550 |

| WOW... everyone got the same answer as me. slant line thro =... really it could be either. I though i was the only one who would get that. |
