Small correction! At 12:45 I haven’t multiplied 2√2 by 7 when simplifying 7√8. The answer for the first question should be 35 + 10√3 - 14√2 - 4√6 🤦🏼‍♂️ - sorry! Sometimes by brain goes into auto pilot while I’m recording!!

i always found surds so hard. after literally watching 3 of your videos on it, it is insanely easy . u are actually a legend. please never stop :)

[xkhanz]

13:23 I think you forgot to times the 2root2 by 7 because there is 7 lots of them. So In the final answer you have -2root2 but you should have -14root2 if I’m not mistaken. Sorry if this is confusing.

hands down saving my exams. praying for a grade 7 and going through your playlist im hoping I can do all the videos before my exam starts !!

I’m pleased that you made the small mistake at 12.45. Makes me feel forgiven when I drop a number or a sign etc if you do it occasionally too. I spotted it because I was working along with you, glad it wasn’t my imagination.
Great vids all round anyway. I am in year 1 of a maths degree, I did A level maths years ago and it’s great to have such clear and easily accessible tutelage these days. Incredible how much I have forgotten after 20 years of being out of education.

Mr GCSE Maths Tutor, I think u made a mistake at 13:32.I’ve tried multiple times and my answer was correct which is 35+10root3-14ROOT2+4root6

[ruslana]

[docteramma]

Amazing u always take me from 0 to 100

[Sebskiiii]

That last question was bugging me so hard, spent a whole 15 mins trying to think of a way to turn the negative into a positive to answer the correct form. What a weird way to write a question aha. Anyway, great vid as always! Cheers

While I’m watching your videos I have flashbacks of not paying attention in class while we where covering this

[dristyrahman]

Thank u soo much this videos are helping me a lot

[batoolalmousawi]

hey, sorry quick question for question 13:24 the second one could I simplify 3√10 to 3√5 and 3√2 and then add them with the other surds. like 9√2 and the new 3√2 and likewise with the 3√5 and 5√5
so the total answer would be
15+12√2+8√5
just a questions thank you :))

[dwcLDN]

Lol seems like im commenting too much but i've really got to appreciate what u do thanks man

[miaciano]

This was so helpful, thank you... your videos are saving my grades hahah! Just wanted to quickly point out that I think that for the (5-√8)(7+2√3) question, you simplified -7√8, and accidentally forgot to multiply it by 7 again? so the final answer should be 35+10√3-14√2-4√6 :))
