Ratings and Reviews
Clear, simple steps.
I enjoy maths  this is like a relaxing game for me... keeps the brain nimble. I like the simple interface  not cluttered with whizzbang graphics BUT I would love to see a couple of simple changes in the "play" area...
1. Take away the multiple choice solutions! This steals half the fun. I want to do the math  apply the solution and then perhaps the app would match the result. There's satisfaction when you know you've grasped the concept.
2. A pencil and eraser to practise on the graph paper background  right where the problem is being explored. At the moment I swipe in and out of a notepad (well maybe not so simple to add ).
3. Some complex questions combining more than one "trick" and/or... (maybe this is a new app?) a way to build your own problem where the app calculates the solution and matches to your result.
Awesome!!!
Easy steps, works great and a lot of fun!
Great app, opportunity to be greater still
Love this app, however it would be a better test of ability to ask for the answer rather than to supply it in a multiple choice the app would achieve it's aim much more effectively. If after say 3 failed attempts perhaps the answer could be supplied along with a prompt for more practice, just a thought!
