Harvard CS50
FreeCS50x: Introduction to Computer Science
Harvard’s CS50x introduction to computer science, with challenging problem sets and a final project beyond the lectures.
University of London — Omar Karakchi
Explore the University of London’s computing mathematics course on number bases, arithmetic, sequences and series as a foundation for further study.
Opens on the provider’s site. Check current access and certificate terms there.
The University of London introduces mathematical ideas used to represent and manipulate information. Number bases lead into sequences and series, with attention to how quantities are expressed numerically. It suits learners who want to strengthen the mathematics beneath introductory computing rather than begin with a specialized software framework.
Beginners strengthening mathematical preparation for computer-science study; preview the sample calculations first.
Allow time to solve exercises independently rather than only following explanations. Software versions and setup instructions can change; compare them with current documentation. Mathematical and programming foundations develop through repeated practice, and completing an introductory course does not demonstrate expertise in every computing field.
Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.
Convert a small set of values between decimal and binary, then check each conversion by reconstructing the original value.
