      My friend was a math teacher. She says I use algebra all the time without realizing it.

    These calculations on the board don’t make sense without context.
    If the problem is 6/16=12/x then x=32.
    The last line is either a mistake (wrongly shortened division of the above) or a new problem.
    Then 3/8=6/x => 3x=48 => x=12.

    And now to Covid spread calculations with exponential growth… πŸ˜‰

      I looked at that and even I thought it was wonky. It is no wonder the kid felt perplexed.
