A student identified the terms of the expression 9a+4b−18 as 9, 4 and −18. Explain the student's error.
Identify the correct answer.

Answer/Step-by-step explanation:

A term in an algebraic expression is a number standing on its own (constant), a letter (variable), or a number multiplying a variable (coefficient * variable).

Given the expression, 9a + 4b - 18, there are three terms in the expression, namely: 9a, 4b, and -18.

The student made an error in identifying the terms properly by excluding the variables, a and b, in the first term (9a) and in the second term (4b), respectively.

The correct terms are: 9a, 4b, and -18.
