Anshay has 123 pokemon cards. Sarah has 213 pokemon cards. Which digit in Anshay's number is worth 10 times the value of the same digit in Sarah's number?
1!
Anshay has 123, which we can break down as 100 + 20 + 3.
Sarah has 213, or 200 + 10 + 3
So the digit in Anshay's number worth 10 times the value in Sarah's number is 1, because 100 is 10 times 10!
