Questions about free mathematics courses
Which maths do I need for machine learning?
Linear algebra, calculus and probability are the usual foundations. Several courses here cover each one.
Are the certificates really free?
Each course card states the certificate status: free means the provider issues a certificate or badge at no cost, paid means the learning is free but the certificate costs extra, and none means no certificate is offered. Always confirm on the provider's page before you enrol, as policies change.
Where do I enrol?
Every course links straight to the provider's own page. We do not host the courses or take payment; you sign up with the provider directly.
