> Failure to understand math leads to a lifetime of poor financial decisions

Failure to understand a few basic mathematical principles leads to a lifetime of poor financial decisions, but the underlying math is something a 10 year old can handle – as can anyone with a calculator.



A calculator is of little use to someone who does not understand mathematical principles. I've seen that in action many times.

The calculator is just a tool to get the precision needed. If you understand the concepts, you can get a rough idea of what '17%' is and whether that ballpark is acceptable.

You whip out the calculator only when you need the precision.
