Terms are the parts of an expression that you add together to create an expression. Constants: These are terms with no variables, so they are a single number. In the expression above, "3" is the only constant. Sometimes we call it a "constant term". Coefficients: The number in a term that multiplies a variable (or set of variables). Thus, "2" is the coefficient in the term "2abc" and "14" is the coefficient in the term "14d" and "1" is the implied coefficient in "e". Some terms are quite complicated, particularly when they involve fractions and parentheses and aren't "reduced" to the simplest form. So it is appropriate to talk of expressions within expressions. For example, if I see the equation (an equation is simply two expressions that are equal to one another) here: Then I can talk about "terms" within the (4r  2), or (9+t) and so on. I hope this helps.
