I hate having ads on Multiplication.com. I’m a parent of two girls and was a classroom teacher for over 25 years. The number one goal of the website is to help kids learn the times tables. I hate having ads on the site but each week millions of kids log onto the site and play the games. The bandwidth for the traffic costs me between $3000 and $5000 a month. The only way I have been able to keep the site operating is having some type of ad generated income.
