Question 521039
Think of math as a big pyramid. The base is an
understanding of fractions, addition, subtraction,
multiplication, division, our decimal number system.
Then above that is the very basic rules of algebra,
including equations, exponents, more addition,
subtraction, multiplication, and division rules.
---------------------------------------
The point is, if you missed something down below
on the pyramid, you must go back and clear it
up completely, or it will come back to haunt you
later, like a poorly built pyramid.
----------------------------
Eventually, you won't have to keep going back to
clear up things you missed.
