STACK: partial credits for correct calculations with wrong values

Hi,

I am looking for short examples on how to implement partial credits for correct calculations with wrong values with STACK (I am a newbie).
What do I mean (simple stupid sample question):

Q1) Given a rectangle with sides a=10 and b=20. Calculate the area A.

Q2) You have 10 such rectangles. Calculate the sum af their areas.

A student gives these answers:

A1) A=300 (wrong, no points)

A2) Sum A=3000

The answer A2 is wrong of course but the calculation 10*300=3000 is correct, so the student should get some partial points for this correct calculation.

Stefan

There is a question like this in the STACK demo quiz, so try to find it and see how it is built. (The STACK demo course comes with the STACK question types. Look for a Moodle backup file in question/type/stack/samples_. Basically in marking part A2, you compare the student's response with 10*A1.
