For those who are not math nuts, Jack is writing out a definition for the Definite Integral. Where, you find the integral, then plug in the upper and lower limits and find the difference as the solution. Or,

The integral of a function is the anti-derivative of that function plus the constant that is lost, C.

A derivative of function f(x) is written as f'(x) dx.

Thus, the integral of f'(x) dx is f(x) + C.

Now the definite integral of f'(x) dx with the bounds of (a,b) can be written as:

( f(b) + C ) - ( f(a) + C )

The C, constants, cancel out, leaving the definition:
⌠b
⌡a f'(x) dx = f(b) - f(a)

You learned something.. maybe...

Also, for those that know the value i, or those who's brains are not hurting yet;

We know that i is defined as √(-1) (√ is used here as square root) Thus we have the following;

i = √(-1)

i² = -1

i * i = -1

√(-1) * √(-1) = -1
The property of square roots stats such that √(a) * √(b) = √(a*b)

√(-1 * -1) = -1

√(1) = -1

1 = -1

Mmm delicious.

From there, if we add 1 to both sids;
2 = 0

Divide by 2,
1 = 0

Add 4 to both sides,
5 = 4

Hey! Look! I proved 2 + 2 = 5!!!
Or we can take that 4 away,
1 = 0

Times 12,
12 = 0

Plus 42,
54 = 42

6 * 9 = 42. I fixed the universe.
