The only teacher that can actually teach maths. Been scrolling a while on KZbin & got stuck. Now I just need to practice examples & I'll be ready. Thank you Sir.

I never knew you were still uploading videos up until I, actually came across this channel and not on the website. Thank you.

[@ExamSolutions_Maths]

Yes, still making videos

@@ExamSolutions_Maths keep up the great work. It have saved me and helped me refresh my mind on maths that i have not been studying for 5 months, cause of the lockdown and no online studies.

Could you do a video on how to determine whether there is a unique solution of a simultaneous equation, where you have a variable as a coefficient, and then determine if the equation is consistent or inconsistent. (for example question 9 on OCR FP1 June 2015). Thanks, love your videos, they are very helpful, especially in further pure!

I have liked yr lessons sir

[@sheilacavino7294]

we want a clear procedure how to come up with unknown numbers and such calculates are not recommended in an exma room

[@ExamSolutions_Maths]

These calculators are allowed in most exams.

[@resin1682]

I need that calculator you are using

[@Joycekanjedza]
