    • @SwiftNinja69swithwaifus
      @SwiftNinja69swithwaifus Před 2 lety +2

      no you still need to show sufficient workings, but this method can be used to check your answer or help you if you don't know how to approach the question.

    • @MathinarUK
      @MathinarUK  Před 2 lety +5

      Technically, correct answer means full marks for 95% of questions. Even without working out. However if you made a typo putting the numbers into your calculator, this will result in zero marks without working out. So you use this to check that your answer is correct rather than rely on this to work out your answers

    • @MathinarUK
      @MathinarUK  Před rokem

      You can’t just type in a quadratic simultaneous equation and get it to produce an answer. You need to substitute the linear equation into the quadratic and use the calculator to solve the quadratic equation.

    If the question is a high mark question (3/4/5/6) and it doesn't specify whether or not you have to show your working, will you get full marks if you show no working but get the correct answer? AQA Maths btw
