Well I hope that you were trying to figure out the difference in the shape of the two numbers that they are vertically opposite to each other, etc., but the original difference is 3.Hide Answer Show Answer

huh?

The trick is you were looking for the trick but there was none.

good one

Yea got that 1

so he's saying the correct answer is 3. so what's the trick?

Numbers are so abstract, and people tend to think in pictures, shapes, etc. Taking that into context, the obvious answer would be the shape of the numbers. This one was quite amusing, but I doubt it would get past any mathematician :-)

I don't like that.

Actually, the way the question is posed, the answer should be -3.

good 1

NO RAB, BECAUSE THE DIFFERENCE ON A NUMBER LINE WOULD BE 3 PLACES...IT DOESNT SAY WHAT IS 2 MINUS 5. JUST ASKS FOR THE DIFFERENCE, AND THE DIFFERENCE IN PLACEMENT IS 3.

I think rab is correct. Difference is the result of a binary operation (subtraction) on the first and second terms. So in algebra, the difference between x and y is (x-y). Just like the quotient of 12 and 4 is 3 not 1/3.

What does it mean by "vertically opposite"?

u mean "-3" cuz (2-5=-3)

you butthole!! I thought i was all smart and you tricked me!!!!!!!

Lol, just kiddin...great teaser!

Lol, just kiddin...great teaser!

difference means 'when you subtract', so the difference between A and B is A-B. the answer is -3

I think there's a lot of fluff in the answer that should be removed. 3 (or -3) is the answer, right? Why tell the reader what you were hoping for them to have done? (If they had done it, they would realize it right away after getting the answer.)

But I think this is a good teaser.

But I think this is a good teaser.

Yeah, I guess it should be -3... Well, this teaser is great. I was thinking along the lines of math, but then it totally caught me off guard when it was a subtraction problem. Soo great!
