Additions Subtraction is a fun app that is the perfect equilibrium between fun and practice. It uses simple concepts of addition and subtraction to help kids of all ages gain proficiency in Math.

All known bugs fixed thx for feedback

Thanks everyone for the great feedback, we have fixed all known issues. We are currently testing this app in two Tanzania and India middle schools to get a feel of how well students do after using this app. Keep up the great feedback to help us improve

Good app

Looks good so far. Wondering if you could have different levels? My 2nd grader does well with filling in the
Blank. But my kindergartner needs a lower level where she is just
Learning adding in the columns. Thx.
