Maths Formulas & Brain Teaser

High hopes - I got this app to help my son practice squares and cubes. It seemed like it would be a great app but the square roots and cube roots don’t seem to work properly. Also even though you can tell when you get something wrong, you don’t get a corrected answer. It would be helpful to have correct answers appear when wrong. Make it more of a game! Really love the idea and it’s MUCH needed for help with math facts.
