    Thank you for taking what, on the surface, appears to be such an intimidating formula and teaching it in such a clear, calm and peaceful way. Leaving the anxiety behind helps one to concentrate on the procedure without unnecessary distraction. I watched your video twice, stopping it step by step to make sure I understood the concepts you were teaching and it all became so clear and simple. I believe I can now apply the binomial theorem without the use of a calculator or Pascals triangle and for me that is an achievement. Thank you again.

But I used to enjoy and learn so much from your video's at work during lunchtime, it was relax and educational at the same time, and so very very clear! So happy you're making awesome video's again!

Its good if u can select pastpapers eg Cambridge Alevel and stuff and do and show how to tackle questions and all. Btw happy to see u back. My sis got 93 for maths from just learning for u.

    Many don't know this, but Binomial Expansion can be used to find roots of a number. Example; (a +b)at n=2 power is a formula for finding a square root of a number, and n=3 power is for cube root and so on.
