For YD, my kid brother, and all the others that stand in the door

 

72

 

Go broncos!!

 

Now don't start that stuff up YD..

 

Typical jock playing with out a helmet...

 

Nothing much to lose.....

Yes.

 

Hmmm... Did your pencil break at 8?

One could argue there are two answers, one mathematical and one philosophical and neither of which are 72.

Have fun.

 

Correction:90

 

Correct, sir!

 

f(x)=x(x+1) is the equation for the mathematical solution if you don't want to work out the pattern.

Technically using the equal sign as they did is not quite kosher. But sticking with that 2=6 we get to the philosophical answer that to claim 2 actually equals 6 is the liberal bovine excrement new methods infecting math in our schools. "Oh, we want them to experience the discovery journey, not worry if they get the right answer."

Kell, Tac,

Here is a good one that while it doesn't prove 2=6, it does "seem" to show algebraically that 2=1:

(1) X = Y - Given
(2) X^2 = XY - Multiply both sides by X (note X^2 means X raised to 2nd power, i.e. X squared)
(3) X^2 - Y^2 = XY - Y^2 - Subtract Y^2 from both sides
(4) (X+Y)(X-Y) = Y(X-Y) - Factor both sides
(5) (X+Y) = Y - Cancel out common factors
(6) Y+Y = Y - Substitute in from line (1)
(7) 2Y = Y - Collect the Y's
(8) 2 = 1 - Divide both sides by Y

Is there an error or mistake? If no, then how can this be (outside the world of the NCTM who promote too much of the math instruction destruction)?

 

We need pictures!
