What number is b in math
[a,b] closed interval [a,b] = {x | a ≤ x ≤ b} (a,b) open interval (a,b) = {x | a b} i: imaginary unit: i ≡ √-1: z = 3 + 2i: z* complex conjugate: z = a+bi → z*=a-bi: z* = 3 - 2i: z: complex conjugate: z =

I think this app help them get good grades in math class, strongly recomend, it's been a lifesaver for mastering math at any level, this app is AMAZING when you put in your problem it ask what you want to do with it like , simplify multiply subtract and more but even better you can just take a picture if you dont want to type it is great.

Math app helps me with the math problems that I struggled with the most, and makes it easier to understand, keep it up This app. Very helpful just loved it. It's very helpful for me and I've been out of high school for almost 12 years and I can't tell you how easy it is to use this app for answer checking but also teaching me new methods.

If set A and set B are two sets then the cartesian product of set A and set B is a set of all ordered pairs (a,b), such that a is an element of A and b is an element of B. It is denoted by A × B. We
