1.

Which symbol would you use to balance the number sentence?

a. | I don′t know. | ||

b. | × | ||

c. | - | ||

d. | + |

So, 8 × 1 = 8.

Correct answer : (2)

2.

Multiply:

a. | 33 | ||

b. | 31 | ||

c. | 32 | ||

d. | 1 |

So the product of 32 and 1 is 32.

Correct answer : (3)

3.

Select the expression that is an example for the identity property of addition.

a. | 4 + 0 = 4 | ||

b. | 4 × 0 = 0 | ||

c. | 4 × 1 = 4 | ||

d. | 4 + 3 = 3 + 4 |

So, among the number sentences listed, only '4 + 0 = 4' is an example of the identity property of addition.

Correct answer : (1)

4.

Pick out the number sentence that correctly shows the use of the identity property of multiplication.

a. | 8 + 1 = 9 | ||

b. | 8 × 0 = 0 | ||

c. | 8 × 1 = 8 | ||

d. | 8 + 0 = 8 |

So, among the number sentences listed, only '8 × 1 = 8' correctly shows the use of the identity property of multiplication.

Correct answer : (3)

5.

Choose the appropriate symbol to balance the number sentence.

a. | > | ||

b. | = | ||

c. | < | ||

d. | + |

So, the product of 3800 and zero is zero.

The product of 5 and zero is also zero.

So, 3800 × 0 is equal to 5 × 0.

Correct answer : (2)

6.

Choose the operation that balances the equation.

a. | - | ||

b. | + | ||

c. | × | ||

d. | ÷ |

So, 3200 × 0 = 0.

Correct answer : (3)

7.

Add:

a. | 0 and 1 cannot be added | ||

b. | 10 | ||

c. | 1 |

[Identity property of addition.]

So, 1 + 0 is equal to 1.

Correct answer : (4)

8.

Add:

a. | 55 | ||

b. | 550 | ||

c. | none of these |

[Identity property of addition.]

So, 55 + 0 is equal to 55.

Correct answer : (1)

9.

Divide:

14 ÷ 1

14 ÷ 1

a. | 13 | ||

b. | 1 | ||

c. | 14 |

So, 14 ÷ 1 = 14.

Correct answer : (4)

10.

Multiply:

9 × 1

9 × 1

a. | 1 | ||

b. | 10 | ||

c. | 9 |

So the product of 9 and 1 is 9.

Correct answer : (4)
