I am a parent of 3 and with all this math learning apps for kids I was missing an option to adjust the ranges and types of equations. I wanted my children to spend time more productively in front of the screen and this can be a way. I tend to give them math exercises before they can play game, this way with practicing everyday they can become better in this essential skill that stays with them for life.
