    I wonder for a long time.
    Why are navigators only capable of addition and subtraction.
    You learn multiplcation and dividing on age 10 to 12?
    So once learned and maintained it must be possible to do this primair multiplcation and dividing.

    Or not? Are we so degenerated?

    I do most calulations on the TI-30XB electronic calculator. From time to time longhand, to maintain the brain.
