Question: I'm having a hard time with these math problems...? here they are...\n\n1+ 4\n3 x 21\n4 - 8

Answer: Man, they sure are being hard on kids these days. You really shouldn't trust people giving you answers here, they most likely pulled their answers from a faulty wikipedia answer. I'd look up the number for your nearest University, call, and then ask to speak to the Dean of the Engineering college. He'd at least have a chance at getting these.
