Answer :

Certainly! Let's solve this step-by-step:

1. Identify the Greatest 3-Digit Number:
A 3-digit number is any number between 100 and 999, inclusive. The greatest 3-digit number is 999.

2. Identify the Least 3-Digit Number:
The smallest 3-digit number is 100.

3. Calculate the Product:
To find the product of these two numbers, we multiply the greatest 3-digit number (999) by the least 3-digit number (100).

4. Perform the Multiplication:
[tex]\( 999 \times 100 = 99900 \)[/tex]

Thus, the product of the greatest number of 3 digits and the least number of 3 digits is [tex]\( 99,900 \)[/tex].
