Not True Statement:
Zero is the identity for multiplication of whole numbers.
Explanation:
Associative Property:
- Addition and multiplication are associative for whole numbers.
- Associative property does not affect the value of the expression when the grouping of numbers is changed.
- For example: (2 + 3) + 4 = 2 + (3 + 4) and (2 × 3) × 4 = 2 × (3 × 4)
Commutative Property:
- Addition and multiplication both are commutative for whole numbers.
- Commutative property does not affect the value of the expression when the order of numbers is changed.
- For example: 3 + 4 = 4 + 3 and 2 × 3 = 3 × 2
Distributive Property:
- Multiplication is distributive over addition for whole numbers.
- Distributive property is used when we multiply a number by a sum or difference of numbers.
- For example: 2 × (3 + 4) = 2 × 3 + 2 × 4
Identity Property:
- An identity element of an operation is the value that, when used with that operation, does not change the value of the expression.
- For addition, the identity element is 0, because adding 0 to any number does not change the value of the number.
- However, for multiplication, the identity element is 1, because multiplying any number by 1 does not change the value of the number.
- Therefore, the statement "Zero is the identity for multiplication of whole numbers" is not true.
Conclusion:
- The correct answer is option B, which states that zero is the identity for multiplication of whole numbers, is not true.
- The identity element for multiplication is 1, not 0.
