Most of their answers are WRONG. Who created this? Someone in kinder. This is shameful and disgusting. By the way, this is a college math professor analyzing your app. PAY SOMEONE TO GET THE RIGHT ANSWERS. DO NOT USE THIS APP
Some of the questions in the equation and percentages said the correct answer was wrong I went back and tried all of the answers and it said they were wrong also
Thank for this wonderful app. I finally found an app that's helping me with my algebra problems! I wish I could rate it 100000000 stars!
Finally found a app. That I can understand at my own pace! Algebra one should be a breeze for me when I finish!
I really love this app but it stops a lot, but for what its teaching me. Its priceless.
This is a great app to refresh your algebra skills or to learn prealgebra but it shuts down often and when I put the correct answer in it records it as wrong. Fix these things and it would be great!
1-6 subtracting integers. Problem, 2-(-5)=7. recheck all of your questions and, show more examples the quick, fast, and easy method does not always work!
Wish I have known about this sooner. Love this App. Outstanding Guys.

Helps brush you up on math when you forgot it!
It doesn't let me ha e what I need and I need help with pre algebra I am only in the 6th grade
This app is great
I was doing the test for the very first section and i got to the question 3x+9x if x=1 which obviously the answer is 12 which was letter d, but it was say I answered wrong, the results would say I answered C for it when I hit the letter D. I tried it 6 times and even my wife tried it, I hope I was specific enough in my description to help identify the problem, I hope it gets fixed.
Some questions are not correct with answers. For example. The question with x-10.46=-11.56( I think it was like that) the correct answer it -1.1 but they are putting the correct answer as 1.1 please fix it
