Exactly what I was going to say. Modular arithmetic and number theory give you the ability to use your own tricks whenever you need them (don't try to memorize that wikipedia list). The wikipedia link given doesn't do the theory behind the techniques justice. If you want to learn some similar...
Any "trick" would have a mathematical underpinning for why it works and therefore I would consider it useful. The rule of 3 is a good example- if a number's digits add up to something divisible by 3 then the number itself is divisible by three e.g. 141 1+4+1=6 so it is divisible by 3. This is...
Hi all, I'm a graduating senior next semester and I need to choose my senior project topic by the end of May. The problem is that I have NO idea where to even start looking. Anyone have any ideas? I am interested in number theory, and some differential equations but NOT linear or abstract...
IMO, you'll be fine. I didnt take school seriously and got a D in Calc I my freshman year but after getting serious I became a math major and took calc II,III, advanced calc, diff eq etc.. without retaking calc I and I didn't struggle once. Truthfully, you'll probably never have to do those hard...
Are there any good websites that give examples and offer help in Abstract Algebra? I have an awful professor that doesn't use a book and gives bad notes. Needless to say, I'm struggling.
