We also watch lots of videos. Measuring pi with pies (numberphile) and “The Sounds of pi” are my favorites.

I find most have issue with this because of confusion between infinity and an infinite number of things.

]]>Example #1

12 x 34 =

Step 1: 2 x 4 = 8. This will be the last digit in the answer.

Step 2: 2 x 3 = 6. Add 4, and you get 10. The the “0” will be the next digit in the answer and the digit “1” will be added to 3 to get 4.

Final answer 4-0-8

Example #2

13 x 37

3 x 7 = 21, “1” will be the last digit in the answer and “2” will carry over to the next step.

3 x 3 = 9, 9+7+2 = 18, “8” will be the next digit in the answer and “1” will carry over to the next step.

1 + 3 = 4. “4” is the final digit.

Answer is 481
