SIMPLE ALGEBRA WITH A VARIABLE QUANTITY REPRESENTED BY A LETTER
Since my last post we have completed the last of Doman’s suggestions – equations with a variable. Following his suggestion included in the book „How to Teach Your Baby Math,” I replaced the letter “x” commonly used as a variable with the letter “y.” This was necessary because the letter “x” is similar to the multiplication sign and this may confuse a baby.
