Hi Hypnos 14th,
Khan Academy community Zendesk always loves to hear feedback from there students while it takes a partnership to develop content for Khan Academy your it's quite possible in the future that new mathematical content will be added.
Thanks for using Khan Academy should you have any questions in future I will be happy to help you!

Thanks for the reply hopefully it'll come anytime soon
