Q. Indigo is organizing textbooks on her bookshelf. She has a Spanish textbook, a math textbook, and a physics textbook. How many different ways can she line the textbooks up on her bookshelf?

Permutation Problem: We are dealing with a permutation problem where the order matters. Indigo has $3$ different textbooks to arrange on her bookshelf. To find the number of different ways she can line them up, we use the formula for permutations of $n$ distinct objects, which is $n!$ ( $n$ factorial). $\newline$ Calculation: $3! = 3 \times 2 \times 1 = 6$
