Grade: 7-a Lesson: S2-L6 |
Explanation: The best way to understand algebra is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
1. Determine the value of expression \$b^3 + t^2 + 2bt - 16\$ when b = 3 and t = 1.
Step 1a
|
|
Given expression. |
|
Explanation:
Given expression \$b^3 + t^2 + 2bt - 16\$ is an algebraic expression in variables b and t and value of b = 3 and t = 1. |
|
Step 1b
|
|
Substitute the value of variable |
|
Explanation: Substitute the value of variables b = 3 and t = 1 in the expression. \$b^3 + t^2 + 2bt - 16 \$ \$=> (3)^3 + (1)^2 + 2(3)(1) - 16\$ |
|
Step 1c
|
|
Perform the opreartions among the terms to determine the value of expression. |
|
Explanation:
Perform operations among the terms \$=> 27 + 1 + 6 - 16\$ \$=> 34 - 16 \$ \$=> 18 \$ |
