Remember
Remember is a place I put random stuff that I find interesting in case I forget about it or some thing I would like research more in depth later.

$$\sum_{n=0}^\infty 2^n = -1 $$.

$$5! = 1\times2\times3\times4\times5 = 120$$

$$\Pi = 3.14159265358979$$ I'm working on memorizing 25 digits of π

$$\lfloor1.4\rfloor = 1 $$ The floor and ceiling functions give us the nearest integer up or down.

$$\lceil1.4\rceil = 2$$ The floor and ceiling functions give us the nearest integer up or down.

21, 4, 0, and −2048 are integers, while 9.75, 5 1⁄2, and √2 are not.
