    • Ever witnessed someone who couldn’t do simple math without a device? Obviously, I’m not talking about those with some type of challenge.


      • Nope. I despised math growing up, once I got to geometry. However, Base-10 math is not a written math and algorithm math isn’t supposed to be mental math. I will never teach base-10 math because I know my daughter isn’t “wired” to see numbers that way. She’s taught the way she responds best to. That’s why home education students test higher than public school kids. They are taught in a way that works for them; not for the majority.

      • We must be referring to 2 different systems. I studied mathematics at university and its definition is built entirely on a 10 number representation based on the decimal system, but I digress. Maybe there is a new base 10 of which I am unaware.
