You have four tiles that say M, A, T, and H. How many words can you form from these tiles, if the letters must be in alphabetical order? For example, you can form "AHM" and "HT". (The words do not have to be valid English words.)

A , H , M , T

 

Taken one at a time =   4 words

Taken two at a time =  3 + 2 + 1  =  6 words

Taken three at a time  =  2 + 1  = 3  words

Taken four at a time  = 1  word

 

So   4 + 6 + 3 + 1 =   14  words
