    i swear this topic is harder and more confusing than whole igcse syllabus. after the day i studied this topic, i forgot almost everything. also roundings are similarly hard for me. i know it looks actually pretty easy and for most of the people it is easiest but for me, it's exactly not. i hope i won't miss a* just because of these type of question because it's sooo confusing (btw my teacher said that i always make mistakes in supereasy questipns especially first questions of ig are generally so easy. but peraonally, i think that studying harder questions instead of basic stuff makes more sense. but i lose marks just because of basic things and this makes me soo sad.

    Sir what if a value is to the nearest significant figure like 2 how do we approach it .I understand that
    1 decimal places=0.1 so 1 significant figure will equal what?

    • @GingerMathematician
      @GingerMathematician  Рік тому +2

      If a value is given to the nearest significant figure, it means that only one digit is certain and the other digits are uncertain. For example, if a value is given to one significant figure, it means that only the first digit is certain and the other digits are uncertain.
      In terms of decimal places, one significant figure is equivalent to one decimal place. So if a value is given to one significant figure, it means that it is accurate to one decimal place.
      To answer your question specifically, if a value is given to the nearest significant figure of 2, it means that it is accurate to one digit after the decimal point or to the nearest 0.01. This is equivalent to two decimal places.
