It even has a calculator you can use in the app! I really love using this because I can check my answers and if I got it wrong I cab see what I did wrong with the apps problem explanation. Almost no adds at all and can understand even my sister's handwriting.

Zachary Mogensen

This app is simply amazing. It is the most reasonable math app I've seen, it's a great way to check my answers or help when I'm stuck and can't figure it out. It's very useful for homework help, explanations, and checking your answers.

John Spiro

Very impressive, i've only been using it for a few minutes but it reads pictures of equasions perfectley and always gives a perfect awnser. The app is pretty good, however it doesn't have an option to solve a question to get an answer in its different form, like exponential form.

What is the difference between coefficient of determination

In order to understand correlation, we need to discuss covariance. The variance of a random variable A is v a r ( A) = E [ ( A − E [ A]) 2], where E [ A] is the expected value of A. The variance is a measure of the spread or dispersion

Coefficient of Determination (R Squared): Definition, Calculation

R Squared Formula = r2 Where r the correlation coefficient can be calculated per below: r = n (∑xy) – ∑x ∑y / √ [n* (∑x2 – (∑x)2)] * [n* (∑y2 – (∑y)2)] You are
