It reminds me of what I told my kids about mathematicians being lazy and inventing ways of skipping work. For example, instead of repeated addition, find tricky ways to do multiplication. Or that fractions are just delayed divisions—we postpone doing the division as long as possible—including many multiplications on the way too (canceling down). Or think of summation rules.
