Lily wants to use the inverse to check this calculation.

Which answers are correct?

699 + 3000 = 3699

• 3699 - 3000 = 699

• 3699 = 3000 + 699

• 3699 - 699 = 3000

• 3000 = 3699 - 699

Miss Dixon writes this question on the board.

The class round it to the nearest 1000 and approximate the answer.

Which answer is correct?

4,395 + 1,531

• 6,000

• 6,500

• 7,000

• 5,000

• 8,947 + 8,631 = 17,468

• 8,947 + 8,521 = 17,468

• 8,251 + 8,947 = 17,468
