Now, let's consider any two whole numbers, 4 and 9.

[tex]\[4 + 9 = 13\][/tex] (13 is a member of the set of whole numbers)

[tex]\[9 - 4 = 5\][/tex] (5 is a member of the set of whole numbers)

[tex]\[9 \times 4 = 36\][/tex] (36 is a member of the set of whole numbers)



Answer :

Let's break down the solution step-by-step for the given problem involving the two whole numbers 4 and 9.

1. Defining the numbers:
- We are given two whole numbers: 4 and 9.

2. Performing the calculations:

a. Sum:
- We calculate the sum of 4 and 9.
- [tex]\( 4 + 9 = 13 \)[/tex]
- Therefore, the sum is 13. Notice that 13 is a whole number.

b. Difference:
- We calculate the difference between 9 and 4.
- [tex]\( 9 - 4 = 5 \)[/tex]
- Therefore, the difference is 5. Notice that 5 is a whole number.

c. Product:
- We calculate the product of 4 and 9.
- [tex]\( 4 \times 9 = 36 \)[/tex]
- Therefore, the product is 36. Notice that 36 is a whole number.

3. Results:
- The sum of 4 and 9 is: 13
- The difference of 9 and 4 is: 5
- The product of 4 and 9 is: 36

So, the final results of the calculations are:
[tex]\[ \text{Sum: } 13 \][/tex]
[tex]\[ \text{Difference: } 5 \][/tex]
[tex]\[ \text{Product: } 36 \][/tex]

Each of these results (13, 5, 36) is a member of the set of whole numbers.
