The numbers between 32 and 53 are 33, 34, ..., 52.\nTo find the count: $$(53 - 32) - 1 = 21 - 1 = 20$$\nThere are 20 whole numbers between 32 and 53.

Question 1

What is the smallest whole number?

Accepted Answer

The collection of natural numbers along with zero forms the set of whole numbers (0, 1, 2, 3, ...). Therefore, the smallest whole number is 0.

Question 2

What is the successor of 100199?

Accepted Answer

To find the successor of a number, we add 1 to it. $$100199 + 1 = 100200$$
So, the successor of 100199 is 100200.

Question 3

What is the predecessor of 208090?

Accepted Answer

To find the predecessor of a number, we subtract 1 from it. $$208090 - 1 = 208089$$
Therefore, the predecessor of 208090 is 208089.

Question 4

How many whole numbers are there between 32 and 53?

Accepted Answer

The numbers between 32 and 53 are 33, 34, ..., 52.
To find the count: $$(53 - 32) - 1 = 21 - 1 = 20$$
There are 20 whole numbers between 32 and 53.

Question 5

Which element is known as the additive identity for whole numbers?

Accepted Answer

When 0 is added to any whole number, the sum is the number itself ($a + 0 = a$). Thus, 0 is the additive identity for whole numbers.
