My physic teacher used your videos to teacher us, so I watch your video to self study during quarantine period

I feel like estimating is the most stupid sort of mathematics
You don't get the right answer and it's sometimes hard to estimate the answer that your teacher wants

Are you planning to do more advanced maths videos, such as further maths gcse and a level?

[SethyWethy]
