Never quit looking at the cute girl on your left. She might bring a whole lot of fun into your life. On the other hand, your bigmouthed teacher might also bring a whole lot of fun into your life if you learn what he's teaching. Because maths can be fun. And even if you don't find it so, learning the lessons might get you the sort of exam results that get you a good job and a good income, and the cute girls often come with that too.

I am surprised that you took those brackets for multiplication. They were just to explain you that their sum had to be reduced by 6.

I just am a learner that needs to be told a formula, have a chance to do the formula, and then have someone watch me and see what I am doing wrong. Otherwise the 30 mins of lecture just is not retained. Thank goodness for this website as I have no one else that understands math around me.

"(x + 4+5x)6" doesn't have multiplication. You treated it as 6(x + 4 + 5x), which is different.
