Wow, tons of math lessons! I bet I used to be able to do math like this! I took my last math class in 1996 as a senior in high school. My then Calculus class gave me college level credit and it was all I needed. Now I'm homeschooling my kids and will be doing higher level math again soon. Should be fun to see how quickly it comes back! :) Thanks for the post. Have a great day!
Thank you so much really trying to teach children the basics first. It is so important.
