      @bottyboy2381 3 роки тому +3

      Practice makes perfect, I didn't believe this statement when I started competitve programming but it certainly is the case here; GCSE maths is repetition and memorisation, start from the bottom and work your way up, scout the internet and join communities that can help you out on questions you are currently stuck on. In addition, you should also notice your weaknesses and strive to work on them. Linking back to the "strive to work" aspect of my "motivational message", you should spend multiple days really trying to grasp the topic at hand before making an assumption on whether you don't or do understand, I apply this knowledge in my own life and believe me it works.

    • @TheGCSEMathsTutor
      @TheGCSEMathsTutor  2 роки тому +1

      Don't forget that when rearranging a formula there shouldn't be any multiplication symbols! so 8x4 would be written as 12, but if you are multiplying the whole side by 4 then you would write that as 4(y+8) = x or 4y + 32 = x

    Y = X/4 - 8 ... I don't understand how when you add 8 to both sides, you add it to right side and don't really do anything with it. And I get that it's changing the subject, not finding the value, but it goes from Y = X/4 - 8 to Y + 8 = X/4 and I understand how you get to that formula, but I don't understand how you +8 to 8 and then it just kind of gets forgotten for the rest of it.
    Or is it because it's Negative 8 + 8 which is 0
