What is the product of the two largest one-digit primes and the largest two-digit prime?
I know that the largest one-digit primes are 5 and 7, and the largest two-digit prime is 97. So the product of these three numbers is 5 * 7 * 97. I can use the distributive property to multiply 5 and 97 first, and then multiply by 7. Multiplying 5 and 97, I get 5 * 97 = 5 * (100 - 3) = 500 - 15 = 485. Multiplying 485 and 7, I get 485 * 7 = (400 + 80 + 5) * 7 = 2800 + 560 + 35 = 3395.
