Introduction

Here we are dealing with algebraic expressions. We evaluate algebraic expressions involving multiplication or division operations only.

Problem 1

For example, evaluate the algebraic expression z ÷ 9, z = 54

Solution

Step 1:

Given z ÷ 9, z = 54; plug in the value of z

z ÷ 9 = 54 ÷ 9 = $\frac{54}{9}$ = 6

Step 2:

So, for z = 54, z ÷ 9 = 6

Problem 2

For example, evaluate the algebraic expression c 9, c = 8

Solution

Step 1:

Given c 9, c = 8; plug in the value of c

c 9 = 8 9 = 72

Step 2:

So for c = 8, c 9 = 72

Problem 3

For example, evaluate the algebraic expression 42 ÷ c, c = 14

Solution

Step 1:

Given 42 ÷ c, c = 14; plug in the value of c

42 ÷ c; 42 ÷ 14 = $\frac{42}{14}$ = 3

Step 2:

So for c = 14, 42 ÷ c = 3
