Ender Hypersonic October 13, 2017 Share October 13, 2017 My 12 yr old son's math 12 years old?? Wah. He skip level ? Link to post Share on other sites More sharing options...
Vid Hypersonic October 13, 2017 Share October 13, 2017 12 years old?? Wah. He skip level ? Didn't skip level... but his Math very advance liao so I'm finding it hard to help him when he has questions. His math tuition teacher has to keep challenging him with harder questions because he find those at school too easy. Anyway, he solved that question I posted earlier by himself before I gave him the answer from one of the bro here. 1 Link to post Share on other sites More sharing options...
