Last Problem:
The product (multiplication) of the digits of a two digit number is 8. When 18 is added to the number, the digits are reversed. What is the number? (This is not so much a math problem but a puzzle to solve).
Answer:
24
4 x 2 = 8. Now, add 18 to 24: 24 + 18 = 42 (which is 24 in reverse).
