The word “MATH” has four letters: M, A, T, and H. To find the number of different ways we can arrange these letters, we use the concept of permutations.

We have four choices for the first letter, three choices remaining for the second letter, two choices for the third letter, and only one choice for the last letter.

Multiplying these choices together, we find that there are 4 × 3 × 2 × 1 = 24 different ways to arrange the letters in the word “MATH.”

So, there are 24 possible arrangements for the letters in “MATH.”
