Hi guys
how can someone test each individual code in a function to enable one understand it better

I am not sure if I got your question right, but I think you mean you want to test each line of a code of a function that you made? You can give a print statement and check what the above value prints and compare it with what it should print and you can do this for all confusing line in your code and later when you have removed all your confusion you can comment/remove the extra print statements.

Hi,
Could someone explain how the second step is calculated please i.e.,
(2×3)+(2×4+0×3)x+(2×2+3×5+4×0)x^2+(7×3+5×4+0×2)x^3+(7×4+5×2)x^4+(7×2)x^5?
