The math teacher, was having children do problems on the blackboard.
"Who would like to do the first problem, addition?"
No one raised their hand. She called on Tommy, and with some help he finally got it right.
"Who would like to do the second problem, subtraction?"
Students hid their faces. She called on Mark, who got the problem but there was some suspicion his girlfriend Lisa whispered it to him.
"Who would like to do the third problem, division?"
Now a low collective groan could be heard as everyone looked at nothing in particular. The teacher called on Susie, who got it right.
"Who would like to do the last problem, multiplication?"
Johnny's hand enthusiastically shot up.
"Why the enthusiasm, Johnny?"
He said, "Because the Bible says to go fourth and multiply!"
