How much time and money do you spend every single day on Instagram, Netflix, or Hotstar?

Strike that, how many years did you spend studying physics, chemistry, or history in school? How often do you use that language in your day-to-day life?

What if I said that a mere 2-hour course could teach you to calculate faster than a calculator itself? Yes, I’m not kidding. 2 hours of theory and just 30 minutes of practice every day, and within a month you will take less time to calculate answers than it would take someone to enter those digits on a calculator.

So, what’s the catch? There isn’t one. This free course is designed to help people from all walks of life. If you’re a student who is unable to complete math exams because the calculations are too lengthy, this is for you. If you are an adult who needs to whip out his calculator for every little calculation when they go shopping, this course is for you.

Complete with instruction videos, assignments, and quizzes, this course is designed to take you from novice to expert in a matter of a few weeks. So, what are you waiting for? Jump in and let’s get started.
