Wonderful FREE app to learn an abundance of math!!
This app is everything I have been looking for as a math-challenged adult homeschooling a tween. We both use it. Me, to brush up on archaic skills tucked way back in my mind from long ago(possibly on purpose!). He, to learn new skills without his math-blind mother interfering with his becoming capable of solving such problems on his own. I give it a 5/5
