^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

So there is going to be 6 different ways in every textbook you put in front, [amount of textbook (4)] x [different ways (6)] = 24 ways

btw there is a easier way of doing this but i forgot ;-;

Answer 2

I believe it's 24 combinations.

Explanation:

I found how many there were when starting with English, and there were six. I multiplied this by four (for the four books) and found 24.

Hope this helps! Have a nice day :)
