a term is either a single number or variable, or the product of several numbers or variables separated from another term by a + or - sign in an overall expression. For example, in 3 + 4x + 5yzw 3, 4x, and 5yzw are all terms. -wikipedia
But it says either a single number...or the product of the several numbers.
So does that mean that 4 is a term, x is a term, and y,z,and w are also terms? In that case how does it affect things like the associative property, does it not allow for an anarchic rewriting of the original expression?
