# FAQ: What math do I need to know for the State exam?

The National portion of the State exam includes 13 questions on 'real estate calculations'.
Most of the math questions you will see involve basic algebra.

For example, you may see a question such as:
If you buy two rectangular lots, each of which measures 244'x250', how many acres will be in the two lots if combined?
To answer this question, you first have to know that 1 acre equals 43,560 square feet (FYI, you should memorize this fact).
Next, you have to determine the square footage of each lot. Since the area of a rectangle equals width x depth, each lot will equal 244' x250' = 61,000 sq.ft..
Since there are two lots, when combined the total square footage will equal 61,000 x 2 = 122,000 sq.ft..
Finally, since 1 acre equals 43,560 sq.ft., the total number of acres in the combined lot will equal 122,000 / 43,560 = 2.8 acres.

The Georgia Salesperson Supplement portion of the exam (the State portion) does not include any math-related questions.
