Book III

In BOOK III we apply our knowledge of numbers to study:

RATIO, RATE, PROPORTION, PERCENT, GEOMETRY, ALGEBRA

KNOWLEDGE IS POWER! Our mortgage calculations are based on interest rates expressed in percentages.

We can use our knowledge to better decide which bank to choose for a mortgage, tax benefit options and a whole host of problems we deal with on a daily basis.

PRACTICE in problem solving gives us the ability to use mathematical concepts in our daily lives with ease.

Refer back to BOOK I or BOOK II if you need to review because the concepts in BOOK III are based on what you learned in them.
