    I went to school in India, and we learned the multiplication tables with a chant that involved a postfix operator called "zaar":

    two one zaar two
    two two zaar four
    two three zaar six
    two four zaar eight
    two five zaar ten
    two six zaar twelve
    …

    We just accepted such a postfix operator as the most natural thing, and freely used it when talking to each other: “what is seven six zaar?” (42)

    Some of us were adults before realizing (and some probably never realizing) that these “tables” we all sang as children had probably started as:

    two ones are two
    two twos are four
    …

    @svat It's almost Reverse Polish Notation, such as older HP calculators used. For example, 2x6 is keyed as 2 ^enter^ 6 ^enter^ x which gives 12.

      @riggbeck @svat my children are made to play https://www.topmarks.co.uk/maths-games/hit-the-button - quickfire times tables questions - and compete on speed. Less dull than chanting but they still hate it

      The problem may be with 'made to play'.

        @timjan @thechris @tessarakt @weekend_editor @svat caught the hint, still didn't catch the meaning.

        @iris @timjan @thechris @tessarakt @weekend_editor @svat If I understood the story, then in other words:
        The points mentioned would be P, A and B, but due to dialect and the structure of the language someone just listening misses the P, because of the phonetical similarity or homophone nature of how P and B are spoken in that dialect. Does it make sense?
        I happen to speak a language that doesn't have native words with "b" and when I say my name, starting with "p", German speaker hear "b".

            Calling @gretchenmcc this would make an amazing @lingthusiasm anecdote / bonus ep?
