comment Calulate the current price of the option?
Just ask on Actuarial Outpost. There are some people here who know these things but not very many. It's been like 6 months since I took Exam MFE so I can't remember exactly how to do it.

comment Find $z$ values for the standard normal variable
Note that about .36 and .1456 is about 0.5, meaning you can probably guess the error.

comment Exam FM problem: Financial calculator necessary for finding $i$ from $a_{\overline{n}\rceil i}$? Edited
I own the BA II+ Professional. I'm sure the regular version is plenty good enough. As far as any other exam you take, the advantage of the multiview will be clear after you use it for a few minutes. You can see around 4 lines of stuff at once. I can't find my TI 30X IIS right now so I can't say much more than that as to why it's better. Look for a comparison online. Think of it this way. It's $20, it may never help you pass an exam (over having the TI 30X IIS), but it'd suck if it could have and you didn't have it. An exam is worth thousands, I'm talking $20 one time.

Buy a financial calculator. You're at a disadvantage if you don't have one. Just because there exists a person who did in fact take the test without one doesn't mean it's the good thing to do. Second, for tests other than FM, buy a TI 30XS Multiview. Again, without it, you're at a disadvantage.

comment Who are some blind or otherwise disabled mathematicians who have made important contributions to mathematics?
Euler became blind later in life and his Wikipedia article suggests he may have sped up his productivity after that with the help of scribes.
