Nice post; enjoyed reading it I am now even more impressed by you than I was before. You see, I am one of "those" who can't add much less do algebra. In fact, I can still hear my high school math teacher telling by parents they should send me to trade school to learn a skill like welding. Fortunately, they did not listen.. . and I went on to fail his course miserably. <div>&nbsp;</div> I do enjoy Sudoku though and work out their puzzles quite frequently on take off and landing.. if I stay away that long. You see, I am that "unfriendly" person on the plane that talks to no one and wear headphones for as much of the flight as they will allow. <div>&nbsp;</div> I am now also a but jealous of you. I wish I could work out math problems.. <div>&nbsp;</div> BTW, were do you find your equations to solve? It seems once you have worked out the solution, working it out a second time may not be as much fun... (smile)... <div>&nbsp;</div> Thanks for sharing <div>&nbsp;</div> Willie

First, you're very kind, Willie. Second, you ask a good question about where to find good algebra problems: I happen to have kept many of my High School level maths books (and beyond). And, third, you're right I probably did do this one the first time round the "wrong" way. :-) That's why I'm susceptible to the idea the method I presented could be improved on.

I'm pointing my friend Peter to this blog post... he loves this stuff!

Agree. Very elegant math. This is fun. Please post some more of these problems. Thank you.

Thanks, Peter (and Bob)! Will try to oblige.

Good Stuff.....I like to apply the formula (a - b)^2 = a^2 -2ab + b^2 and (a + b)^2 = a^2 + 2ab + b^2....nice observation though.....all in all....your post brings back those memories we had solving algebraic equations in math class.
