Maths Mark scheme

So in the 9-1 maths mark scheme there are p1 marks, process marks, rather than method marks. For example:

P1: For selecting the positive value of x and applying Pythagoras to find the hypotenuse

Say if I did the right process but got the wrong answer, because of a wrong sign or number, will I still get the P1 mark?

Do you have an example of a question you were looking at?

This depends. P1 are for a correct process and not really affected by accuracy.

However when you say incorrect sign, this suggests you're doing something like $a^2 + c^2 = b^2$, so mixing up the hypotenuse with other sides. That is a wrong process and so would not get the process mark.

You'll need to a give specific example if you want full clarification, though. Hope it helps

Ok so for that question I worked out the positive value of x to be $1+\sqrt 6$, however I incorrectly calculated the other side of the triangle to be $-1-\sqrt 6$, instead of $-1+\sqrt 6$ but still continued to find the hypotenuse by using Pythagoras theorem, which obviously lead me to the wrong answer.
