Personally, I think math is really fun, although some questions may be frustrating. Last year, in my math class, my teacher showed us a site and told us to do these math problems. Embarrassingly, I forgot to make a four negative and got stuck on 1 problem for the whole class last year. It’s not extremely hard, but I hope you have fun with it!

P.S. It’s like a scavenger hunt, online.
