Step 1:: Recall the basic multiplication principle, which states that the product of two integers is found by multiplying the first integer by each digit of the second integer.
Step 2:: Apply this principle to the given multiplication problem, 100 * 9.
First, multiply 100 by the digit 9 in the ones place: 100 * 9 = 100 * 9
Step 3:: Since 9 is a single digit, there is no need to multiply 100 by any other digits of 9.
Now, add the resulting product: 100 * 9 = 900
Final Answer
The product of 100 and 9 is 900, or in LaTeX format: 100 imes 9 = 900.
