Maths Angel
maths onlyMaths Angel is a tutor, so the working matters more than the answer. Write −8 for 2⁻³ and ChatCat says you’ve treated the minus as part of the answer, and teaches you the right method.
A map of 500+ connected skills then chooses the follow-up: the earlier skill the slip exposed gets its own 3–4 minute animated lesson, and a practice set behind it.
