Numbers and Decimals Commutative and Associative Laws

🎬 Video Tutorial

(0:24) Commutative Law: Allows numbers to be swapped in addition or multiplication without changing the result.
(1:26) Associative Law: Lets you group numbers differently in addition or multiplication, keeping the result the same.
(2:29) Examples of Applying Both Laws: Use the commutative law to swap numbers and the associative law to group strategically, making calculations simpler.

📂 Revision Cards

The Commutative Law allows swapping numbers in addition and multiplication, shown with examples, but does not apply to subtraction or division.

Examples of the commutative law in addition, 77 + 246 + 23, and multiplication, 25 * 19 * 4 with step-by-step calculations.

The Associative Law allows grouping numbers when adding or multiplying, but does not apply to subtraction or division.

Examples of the Associative Law in addition, (127 + 48) + 52, and multiplication, 5 * (2 * 228) with step-by-step calculations.

Applying step by step both the commutative and associative law in addition, 32 + (115 + 68), and multiplication, 20 × (48 × 5).
