If r = 2 and s = 3, what is the value of r + s?

Answer and explanation

Correct answer: 5

Substitute r = 2 and s = 3 into r + s: 2 + 3 = 5. Therefore, the correct answer is 5. The value 6 comes from multiplying 2 and 3, but the expression requires addition. Exam tip: In substitution questions, replace each variable with its given value and then follow the operation shown.
