Rule of 78 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 these calculators using JavaScript, a client-side scripting language.
Please use the latest Internet browsers. The calculators should work.
Please do not put comma in any of the values.
You may need to refresh your browser after each calculation to clear all results.

Comments, ideas, areas of improvement, questions, and constructive criticisms are welcome. You may contact me.
If you are my student, please do not contact me here. Contact me via the school's system. Thank you for visiting!!!
