I didn't know that the last question was that easy. It came up on my mock and I was struggling. I just want to say thank you so so much for explaining it.

[@lordpengz16]

@@parkour.11parkour58 If you dont mind me asking, how much did you get for maths?

[@parkour.11parkour58]

@@lordpengz16 I was most definitely supposed to get 7/8. If I did the exams I would have definitely gotten or surpassed that, but because of covid and all the self assessment grades, I got a 5. But at the end of the day, the grade I got meant absolutely nothing.

[@praseethanair2761]

I'm pretty weak in maths, I don't get concepts easily, but I was surprised at how you can explain just once or maximum twice and I still get it! Thank you very much, TGMT! Much love and take care of yourself

[@mariag2916]

Thank you for including examples with amounts ending in zero. So many videos spit out the same without a variation of different numbers and a mix of significant figures and decimals. And including truncation example. Much appreciated.

why do you sometimes write 'x' in the middle and sometimes write the number given in the question. Please let me know xx

[@becca19216]

at 14:13 i dont understand why you're adding 2.5, instead of just keeping the error intervals as 2395 and 2405? can someone explain pls

[@Sal-lf2gj]

i'm convinced that 2395 and 2405 are basically boundaries for rounding to 2400, and the bounds of the .5's are called the bounds because for some reason that's just how it works. Then you just use the methods to find the error intervals ¯\_(ツ)_/¯

[@user94783]

because 2.5 is in the middle of 5, it's basically what he's been doing for the whole video before that question

[@itsjustshaz1212]

thank you sir

[@Nehselo]

The finest channel ever created

[@ereniusiumbeli2127]

does it matter if you write it with an x or with the number given in the question? I see answers doing both and I want to know if it's relevant or if it doesn't matter considering x is just a substitute ?

[@TheGCSEMathsTutor]

You can use either! Normally if there is a letter involved you would sue that but either way is fine 😁🙏🏼

[@ligasortv7314]

For the examples shown from 13:38 can you just half the number it’s asking for in nearest m,mph,cm etc…?

[@Sophia-ok4ce]

Thank you for the video :) but why do u put x in the middle first and then the number in the middle in the second half of the video

[@TheGCSEMathsTutor]

You can use either! Sometimes the question may specify what to put in the centre otherwise it’s optional 😁🙏🏼

7.5 and 8.5 👍🏼

[@richiegaskill9648]

Not only is this guy good at explaining maths, but the intro music is so good.

[@1saac1saac]

Note to self: 13:38

[@DixieC]

On a test they wrote the question as 16.0 (instead of just 16) and asked to find the error interval, so is it safe to asume they want 15.5

Holy fuck thank you so much man

It’s usually always ok to use the number or a letter, you aren’t marked down for it, but if the question states a latter then you’d normally put the letter in 😁🙏🏼
