Well, now isn't 2 plus 2 equals 4
2 times 2 equals 4

2 times 2 equals 2 plus 2 equals 4
2 times -2 equals 2 plus -2 equals 0 WAIT 2 times -2 equals negative 4 according to mathematics. No teacher nor professor has been able to even do more than stutter explaining this.

3 times 3 equals 9
3 times -3 equals -9

So why is the digit 2 different?
