PopMath is a fun way for kids to practice basic maths. Six pairs of bubbles with numbers float on the screen above beautiful backgrounds. Each bubble contains a number: simply pop the corresponding bubbles! As you progress through levels, numbers increase, and new operators are introduced: subtraction, multiplication and division. Each level shows your time and number of errors, along with an encouraging message, from "well done" to "unbelievable!" You can also pick a specific operator: addition, subtraction, multiplication or division. Numbers go up to 1000 for addition and subtraction, and 20 for multiplication and division. You can also choose to practice a particular table, from 2 to 12! Enjoy and send your feedback laurent@appblit.com
