# Financial Investment Decision Calculators

I greet you this day,

__First:__ read the notes. __Second:__ view the videos. __Third:__ solve the questions/solved
examples.
__Fourth:__ check your solutions with my **thoroughly-explained** solutions. __Fifth:__ check
your answers with my calculators.

I wrote the codes for some calculations using JavaScript, a client-side scripting language.

I used the Formula.js Javascript library for some calculations.

Please use the latest Internet browsers. The calculators should work.

Please do not put comma in any of the values.

For some calculations, you may need to refresh your browser after each calculation.
