It really helped me with explaining math, there are a few math problems, that it can't solve (not scanned and not by calculator), but mostly a really good app, I'd reccomend it. I wanted that to happen. Math app is the world’s smartest math calculator for algebra, graphing, calculus and more.

Really amazing, 5/5. Didn't pay attention in math at all, but this helped me ace my quiz, and helped me understand everything better, very great app, really works on all sorts of math problems, omg I love this app so much it helps you understand the problem it doesn't just give you the answer without explaining.

I spent FOREVER looking for a This app app that actually showed the steps and this did so perfectly! I do wish that I didn't have to pay to get a full in depth explanation but I get that they have to make money somehow so it's not that big of a problem for me, my school is kind of built like a whole bunker so sometimes my problems won't fully go through.

Consequently, the margin of error formula for surveys relates to percentages. When you add and subtract the MOE from the survey proportion, you obtain a confidence interval of the

The formula to calculate margin of error takes the critical value and multiples it by the square root of the sample proportion times one minus the sample proportion divided by the sample size. In mathematical terms, the formula to determine margin of error is represented as follows: Margin of error = Z * √ [ (p* (1 – p)) / n] See more
