    I would need to use my hands or count out loud or do something after maybe two numbers if we are starting at 100.

    Trying it out just now and the only way I can really effectively do it is by subbing 10 and adding three each time.

      That’s literally what they taught my niece to do in math, so that’s not inherently a problem.
