I completely agree, Basic lack of fundamentals in k-12
Addition and Subtraction (Mental)
Multiplication/Division (Mental) Properties
Powers/Routes Properties
Basic Concepts of Fractions (mulitplication,division,Addition, Subtraction)
Order of Operations
Thats ALL they need to teach you k-6, I will never understand why I had to learn how to do math if we happened to be born with 6 fingers and everything was base 6 instead of base 10..... I mean, I guess it might be important, but not when most kids in the 4th grade can't even tell you what 4 + 7 is without using their toes.
I do a lot of math tutoring for friends and family in my spare time, and its a nightmare trying to do algebra problems when they don't even understand the basic concept of subtracting a negative number, multiplying fractions, Dividing fractions, adding fractions, order of operations......... just a nightmare......
