King of Math 2 is a super fun iOS game for ages 10 on up. King of Math has students playing through 125 stages as they solve different basic (i.e. addition, multiplication, etc) Math problems as they unlock levels to become king or queen. Best of all, there are detailed help guides to show players how to solve a problem, and a timer that can be turned on or off.
