Q: This week's challenge is a little tricky. Given a standard calculator with room for 10 digits, what is the largest whole number you can register on it?I must have misdialed while trying to phone a friend; I got Ed Asner instead.
Edit: I was trying to contact the mathematician Edward Kasner who, along with 9-year-old nephew Milton came up with the name "googol" for the large number 10¹⁰⁰.
A: If you type 706006 (or 709009) and turn the calculator upside down, it spells gOOgOL (or GOOGOL). That's a 1 followed by 100 zeroes and is bigger than any regular number you could enter using 10 digits.
