Explanation: The best way to understand algebra is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Simplify the expression \$ 35 + 9 \times (17 - 13) \$.

Step 1a

The given expression is
\$ 35 + 9 \times (17-13) \$
Inside the parentheses, perform the subtraction:

17 - 13 = 4

Multiply the result by 9:

\$ 9 × 4 \$= 36

Finally, add the initial 35 to the product:

35 + 36 = 71

The evaluated expression is 71.

Explanation: Here, after simplifying the initial product, we multiply by 9 and add to yield 71 as the final result.
