I wasn't referring to the bad grammar, I was referring to the manner in which you were asking for help.

People don't learn that way.

"For Heaven's sake! Ok, I guess I have to dig up my Mathematical Tables from somewhere... No wait, I lended it to Barry."
"See what you did? You gave him a fish. Instead you..."
"Shut up! Ok, so you want to teach me to fish. What shall I do?"
"Well, you can calculate the value of Pi."
"How?"
"There are some methods. Some series converge to Pi."
"What are the series?"
"I could tell you that. But it would be like giving you a fish and..."
