The correct Answer is:
Let's analyze each statement one by one to determine whether they are true or false. ### Step-by-Step Solution: **i. The product of a positive and a negative integer is negative.** - When you multiply a positive integer (e.g., +3) with a negative integer (e.g., -2), the result is -6. - Therefore, this statement is **True**. **ii. The product of two negative integers is a negative integer.** - When you multiply two negative integers (e.g., -3 and -2), the result is +6. - Therefore, this statement is **False**. **iii. The product of three negative integers is a negative integer.** - When you multiply three negative integers (e.g., -2, -3, and -4), the calculation goes as follows: - First, multiply the first two: (-2) * (-3) = +6 (positive). - Then, multiply the result with the third: +6 * (-4) = -24 (negative). - Therefore, this statement is **True**. **iv. Every integer when multiplied with -1 gives its multiplicative inverse.** - The multiplicative inverse of an integer x is defined as 1/x. - When you multiply an integer (e.g., 5) by -1, you get -5, not 1/5. - Therefore, this statement is **False**. **v. Multiplication on integers is commutative.** - The commutative property states that changing the order of the numbers does not change the product. - For example, 2 * 3 = 6 and 3 * 2 = 6. - Therefore, this statement is **True**. **vi. Multiplication on integers is associative.** - The associative property states that the way in which numbers are grouped does not change the product. - For example, (2 * 3) * 4 = 6 * 4 = 24 and 2 * (3 * 4) = 2 * 12 = 24. - Therefore, this statement is **True**. **vii. Every nonzero integer has a multiplicative inverse as an integer.** - The multiplicative inverse of a nonzero integer x is 1/x, which is not an integer unless x = 1 or x = -1. - For example, the multiplicative inverse of 2 is 1/2, which is not an integer. - Therefore, this statement is **False**. ### Summary of Statements: 1. True 2. False 3. True 4. False 5. True 6. True 7. False
