Title: Test1

Grade: 6-b Lesson: S2-L1

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

Examples:

Multiply \$ a^2b \$ by \$ 2ab^2\$.

Step 1a

Given expression:

9×( 2 + 4) Apply the distributive property: a×(b+c) = a×b + a×c

9×(2+4) = 9×2+9×4

Explanation: Here, we applied the distributive property of addition by rewriting the expression.

Divide \$8x^3\$ by \$4x\$.

Step 2a

Given Equation:

\$ 10 + (z + 1) = (10 + 7) + 1 \$

Apply the Associative Property of Addition to the terms inside the parentheses.

10 + z + 1 = 10 + 7 + 1

Explanation: Here, we rewrote and applied the associative property of addition.
