Real Number

1. PROPERTIES OF REAL NUMBERS Grade 7 ALGEBRA

2. COMMUTATIVE PROPERTY

3. Is commutative property also TRUE for subtraction and division? NO, commutative property cannot be applied for subtraction and division. Why? Can you give an example?

4. Is 5 – 2 = 2 -5 ? 3 ≠ - 3

5. Is 20 ÷ 4 = 4 ÷ 20 ? 5 ≠ 0.2

6. C ommutative property is only TRUE for ADDITION AND SUBRACTION.

7. Give examples of commutative property

8. EXAMPLE: ASSOCIATIVE PROPERTY 5 + (10 + 2) = (5 + 10) + 2 5 12 + = 15 + 2 17 17 =

9. EXAMPLE: ASSOCIATIVE PROPERTY 2 x (3 x 4 ) = (2 x 3) x 4 2 12 x = 6 x 4 24 24 =

10. Give examples of ASSOCIATIVE property.

11. EXAMPLES OF CLOSURE PROPERTY 2 + 3 = 5 23 + 31 = 54

12. EXAMPLES OF CLOSURE PROPERTY 10 - 6 = 4 11 - 6 = 5

13. EXAMPLES OF CLOSURE PROPERTY 7 x 3 = 21 15 = 5 x 3
