[6] Right. So if you realize that the two 2-digit numbers on the right side have to be multiplied to give you a 4-digit number on the left side, you can quickly reduce the number of calculator attmpts you make...because anything 31 or below only yields a 3-digit number.
And a few attempts at numbers from 32 to 99 should point you to the approximate location of the correct numbers.
[7] No, math is coooooooooool! Trouble is you have to get through the basics, which are often boring, and then struggle with the mental gymnastics, which is hard. But many a time in a math class we'd get a result and I'd think "Wow, cool!" Even if you don't understand them, isn't the thought of imaginary numbers the least bit intriguing?
I was able to do the puzzle algebraically. You do have to know how to get to a quadratic equation, then use the quadratic formula. If you can't recall your algebra, use trial and error.
K, I have numbers that fit. I apply this "key", and I get a silly word that doesn't work. The reverse would have been a GREAT answer, but it didn't work either.

Wow! Solved it by trial and error. That was hard! Sorry for all the Tanganites who hate math.

I used Excel, but the algebraic method would have been faster.

Well, at least you can eliminate more than 1/3 of the 2-digit numbers as being too small to produce a 4-digit answer.

I'm missing a key part of the equation. In what way does 12 = 34 ?

The equation(not really) should be
a (a=1) = b*(b+1)
the a's are not multiplied
So 12=3*4

agree with [9]...math is awesome...you just have to be logical and pay attention to every detail

Oh, that was excellent. (I have no idea what you're getting, [11]. TG if you want confirmation.)
