Stupid.( You forgot to put a period ). Learn math. ( They " L" should be upper case it is the beginning of a sentence). Also you forgot to putt a capital " T " at the beginning of your first sentence. I might add you forgot to put an apostrophe in the word " That's ". What did we learn from this lesson today class? Don't be rude. Because karma is real. And it is a bitch. You said he needed to learn Math. Well, you need to learn proper English. Good day, sir or madam.
