My wife says I can’t even easily and comfortably do additions and deductions within a range of 100 and often teases me for making so obvious mistakes in simple elementary school math level calculations - which would be disasters for a certified or chartered accountant candidate.

I was trained to be an accountant, for just one year or two in the mid-1990s, at an accounting school that enrolled graduates from junior or senior secondary schools. I’ve almost forgotten everything accountant I learned there and have a very hard time revisiting the trashbin where my residual accounting knowledge is located, if any.
