IRR is when the NPV = 0....and yes just a simple calculator question, except there are unconventional cash flows...then you need to be aware of possible MULTIPLE IRR'S...in which the calculator doesn't show (atleast that I'm aware of)
You better make sure you understand this section...I'm sure there will be some theory in NPV, IRR, payback period et cetera...NPV profile is a good thing to fully understand as well....

make sure to go through the advantages/disadvantages of NPV vs IRR for mutually exclusive and independent projects...

GOOD LUCK EVERYONE
