Highly recommend it needed help for math work or math in general. They don't cover everything but they do for most of Algerba 1 and 2. I cant do math tutors because I get upset easily and its much less stressful to teach myself at home and the walkthrougha they have are amazing! I love this so much and thank your for making math so much better and more fun to learn.

I am able to use this when I have problems in math I cant understand. It really helps me with my assignment, it works unlike the caculater I paid over 100 US dollar's for.

The app is really versatile and useful but this one time it simplified 2 to the power of 51 up by 2 when I need to find the ones place. Works extremely well fast checking and exact answers.
