Exercise 3 Page 92

Terms are separated by + signs.

Terms: 7, 4p, - 5, p, and 2q
Like Terms: 7 and - 5, 4p and p

Practice makes perfect
An algebraic expression is a combination of numbers, variables, and mathematical operations. Terms are separated by + signs. With this information in mind, let's identify the terms in the given expression. We will first rewrite it as a sum of terms.

7 + 4p - 5 + p + 2q ⇓ 7 + 4p + ( - 5) + p + 2q We can see that the expression has five terms, 7, 4p, 5, p, and 2q. Now that we know the terms, we can figure out which ones are like terms. Remember, like terms are terms that have the same variable and the same exponent. In this case, 7 and - 5 are like terms and also 4p and p are like terms.
