Add sherp's recommended math courses

[Sooraj-beep]

@IanDeHaan do you have any suggestions?

[IanDeHaan]

The math department systematically destroyed my chances at taking fun courses because I didn't want to take a 4th calculus course, so I did not end up taking as much math as I would have liked. So some of these recommended courses are just based on what I've heard from others.

The classics:

• 117, 118, 217 (calc 1-3)
• 127, 227 (lin alg 1-2)

Cool stuff that's not too hard:

• 322
• 324
• 421 (didn't take this but wish I could have)
• 422

Algebra:

• 328
• 326 (I didn't take this)
• 429
• 428 (super duper extra painful, I didn't take this)

Analysis:

• 411 (didn't take this)
• 417
• 447 (didn't take this)
