It's perfect for math really. This is the main reason I am passing my Honors Algebra 2 Class, not because I use it to cheat, but because I use it to figure out how to do the problems and then use that method to actually do the problems without This app. Has not steered me wrong yet! Love it and would recommend it to everyone having trouble with math.

Please fixed it, i honestly love this app and just help me so much, i broke that rule tho, and used this app to finish the skills, which were really hard, and has a feature to scan the math problems, idk how to explain but this is a great app with no ads, a camera that can adjust the picture, mic to speak with, and anything else in it which is really really good 😀😀😀.

You must be try this app, this is a great app I am a freshman at high school and it is helping me get correct answers on all of my tests and there is a variety of options to choose, it could solve any equation, it was very useful! And extremely simple and easy to use, and that was the very last thing I expected from this! It way exceeded all my expectations! This was a major help with not only amazing explanation, but very accurate,.

Algebra 1 : How to find standard deviation

The formula for standard deviation is the square root of the sum of squared differences from the mean divided by the size of the data set. For a Population σ = ∑ i = 1 n ( x i − μ) 2 n For a Sample s = ∑ i = 1 n ( x i − x ¯) 2 n − 1 Variance
