Advanced equation solving II

OK, let's go step by step:
1: How in earth can -4 -(-2) = -6 ??? Look! Even the minuses with the parenthesis look like a + sign! -4 + 2 = -2!!!!

2: This is probably one of my favorite errors. He decided to treat the numerator of the fraction as if it was completely alone!!! And he didn't stop there, either. He took the denominator and decided that it would be the numerator from there on. Speechless.

3: If anyone knows how a fraction whose numerator is smaller than its denominator , like 3/6, becomes greater than 1, please, let me know. I beg you.
