Algebra Formula Games
Looking for a fun math game hard for 14 years of age?
My sister has 14 years in eight years and has difficulty with math, especially fractions / decimals / percentages, Pythagorean Theorem and basic algebra (the formula of a line). All games math that I can find are really bored or just simple math. She already knows addition and multiplication! Spends much time online and you like games like Neopets and Club Penguin, no one knows something like this (you can play for centuries) that focuses on higher-level math?
