On the Subject of Multiplication

Honestly, this is literally just multiplying 3 digit numbers. My calculator cannot handle this for some reason.

Compute the product of the numbers on the display and enter it using the numbered buttons to solve the module. Use the gray ‘M’ button to cycle through 10 numbers, the red ‘C’ button to clear your input, and the ‘×’ button to submit it.

Notes:

• The input display can only have a maximum of 30 digits.
• The first number in the cycle is ALWAYS colored gray.
• Incorrect submissions will result in a strike and reset the module with, most likely, 10 new numbers.
• Certain applications are required that can calculate values with higher degrees of precision, such as Windows Calculator.
