Learn String Manipulation by Building a Cipher - Step 42

Surround index + shift with parentheses, and modulo the expression with 26, which is the alphabet length.
what exactly is there to do in this part?

here: 3 + 5 x 3 is 18 right? And when you add parentheses to it, like this: (3 + 5) x 3 is now 24. And back to the problem, just think index is 3 and shift is 5 in the case I mention eariler, and when they modulo in python it is this: % so just put all the together with 26!

Im still confused so where do you put it and do you put 26%?

The percent sign ( modulo) goes in front of the 26 in your expression, like this %26. Read over the instructions again out loud and study tytywentoutformilks usage of parentheses (the above comment) from the result of 24 and apply it to index+shift.
