seven from 13. She’s already taken away three. How much more does she need to take
away? We know that seven is three and
four. Let’s take away four more. One, two, three, four. We landed on number six. 13 take away seven equals six. First, we subtracted three to take
us to 10. Then we subtracted four more. Seven is three and four more. 13 take away seven equals six.
