I greet you this day,

Please solve the questions on your own before checking your answers with the calculators.

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

The Wolfram Alpha widgets (many thanks to the developers) were used for some calculators.

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.
