# not understanding two questions for the mathematics course exam

I don't understand how i am supposed to interpret the encoded equation from the arrays given. The answer was to find a_1-b_1. i don't understand how that conclusion was drawn from encoded equation. I would like clarification on that.    The operation for question 12 ( s[0]+m[1] ) i didn't initially understand. but then i remembered briefly in the mathematic lesson that in python that the index loop always starts at 0 instead of 1 like in general math. Is that correct? i would like that clarified.

Hey George,

Regarding Question 11 from the exam, the task is encoded in the expression

You are given the matrices a, b, a_1, and b_1 above. The task is, therefore, to find the following symbols in the matrices and formulate the question.

a[0][0]
a[0][1]
a[1][0]
b[0][0]
b[1][0]
b[1][1]
b[0][1]

The plus signs concatenate the respective strings. Once you've found what the task is, you need to perform it.

Regarding Question 12 from the same exam, s[0] is indeed the first item while m[1] is the second. Once you locate them, you would need to find their sum.

Hope this clarifies the questions!

Kind regards,
