How wide is 9 kilometers

I was skeptical at first but it works, recommendable. In my opinion,we can learn many methods with this app, i am not at all a math person but the breakdown of steps really increases comprehension.

Sometimes it doesn't recognise the characters which is why i prefer to type the problem. 3 it's actually right and precise, it doesn't always get the right symbols put in, also, the premium is a small price to pay for this app.

So then I downloaded it and tried it out on my math homework and it showed me how to do the problem so when I put the answers ,the next day at school my teacher said I had all the answers right, really great app for math and it really helps if you want to prove what you are solving.
