A three-digit number has all digits nonzero. These digits are multiplied together and then this product is subtracted from the original number.What is the largest possible value of this difference?890890901901909909910910990
Solution
The question seems to be asking for the largest possible difference between a three-digit number and the product of its digits. Here's how you can solve it:
Step 1: Understand that the largest three-digit number is 999. However, this number won't work because it includes a zero, and the problem specifies that all digits must be nonzero.
Step 2: The next largest three-digit number with all digits nonzero is 998.
Step 3: Multiply the digits together. 9 * 9 * 8 = 648.
Step 4: Subtract the product of the digits from the original number. 998 - 648 = 350.
Therefore, the largest possible value of this difference is 350.
