How about this...

x = y.
Then x2 = xy.
Subtract the same thing from both sides:
x2 - y2 = xy - y2.
Dividing by (x-y), obtain
x + y = y.
Since x = y, we see that
2 y = y.
Thus 2 = 1, since we started with y nonzero.
Subtracting 1 from both sides,
1 = 0.

Hold on, there seems to be an error there.

This would be the correct way

x = y
Then 2x = xy
Subtract both sides with 2y.
2x - 2y = xy - 2y => 2(x - y) = y(x - 2)
Divide by (x - y)
2 = y(x - 2)/(x - y)
Since x = y, we get
2 = y(x - 2)/0
Multiply with 0.
0 = y(x - 2)
Since (x - 2) = 0
x, y = 2

DIVISION BY ZERO — THIS IS WHY YOU AREN'T ALLOWED TO DO IT

If John has 3 apples

And Joe steals 4 of John's apples

How many apples does Joe have?

If Johnny has three apples and Davie has two apples, why don't they just shut up and eat?

(Bonus points to anyone who gets the reference)

I should make a pro calculator program when i learn to code

I copied some Python script and added on to it so it could do some basic functions like find the equation of a line and the area of a circle and some other stuff.
