How do you interpret parts of an expression, such as terms, factors, and coefficients?

Coefficients - the number part of a term (3x the 3 is the coefficient)

terms - numbers separated by a + or - sign (2x + 3 is 2 terms)
            (But 1/x or sqrt(x) are not terms because their exponets are not positive or a whole number)

factors - expressions that will multiply together to get the original term.
