At dinner the other night, Charles was exploring numbers once again.
Charles: What is a billion one hundred plus a billion one hundred?
Dad: Corwin, you handle this.
Corwin: [thinks] 2 billion one hundred?
Dad: No.
Alice: Yes way!
Charles: Alice, what is it then?
Alice: 16!
Dad: No, but good try Alice.
Corwin: 2 billion two hundred?
Dad: Yes.
Corwin: I was only 100 off, while Alice was way more off.
Dad: Careful, or you’ll be figuring out exactly how much Alice was off.
