It pains me how its 2019 and the fricking Google calculator is less powerful than a solar powered credit-card sized one from the 90s. A single chip made on the earliest imaginable IC processes can effortlessly deal with larger numbers than the lazy ignorant Google implementation. Maybe they can make this an interview question.

Most calculators of that era had a maximum number Of digits between 8 and 12. Perhaps the Hp48 could do this calculation but not any of the credit card calcs.

In bash

  $ echo "print((-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3)" | sed "s/\^/**/g" | python -
  42

You're just using python, using bc is more bashy:

    $ echo '(-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3' | bc
    42

Without shelling out:

  $ echo $(((-80538738812075974)**3 + 80435758145817515**3 + 12602123297335631**3))
  42

In calc:

$ calc

calc 2.12.4.1

> (-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3
