    In the first step, how come you get 23.3 (recurring) when you multiply 2.3 by 10. Shouldn't you get 23? I will appreciate if you explain that bit.

    0:23 - 0:42 the number is 0.473473473... and so on "A dot above the first and last digits that recurr"
    why can't there be dots on top of all those three numbers? Why just the first and last? They're all recurring right? How am I supposed to know 0.4' 7 3' is 0.473 *473473* instead of 0.473 *4343* ? Only 4 and 3 were dotted so I'm a bit confused. Again many thanks!! 🙏🙏

    • @sexistatheist6464
      @sexistatheist6464 3 роки тому +8

      You only put dots above the first and last digits which recur, because that's how things have historically been done in maths. The idea behind that is to show where the recurring sequence begins and ends... and if you recognise that the dots represent the beginning and end of a sequence, it can be taken as a given that every digit in-between the ones with dots above them are also part of that sequence. This can also save time, since if you have to write a long sequence of recurring digits, you would need to write alot of dots as well using your proposed method, whereas the standard practice allows you to show where the sequence begins and ends with just two dots. No will stop you putting dots above all the recurring digits if you want, but you could lose marks in an exam for that, since that's not the standard practice. If you're having trouble making sense of it, just think of the two dots as 'bookends' to the recurring sequence.

      It’s been 2 months but basically you only put dots above the first and last digits that recur. Think of it like this, when there is more than 1 dot above the numbers think of them like brackets; everything inside them will reoccur. Eg
      . .
      0.24687 will recur like 0.246872468724687…….and so on
