If you're confused split it up step by step.
Quotient of 72 and 18 is 72 / 18 = 4
Add 14 to previous result: 4 + 14 = 18
Minus 6 from previous result: 18 - 6 = 12
There's your answer.
The reason i was getting confused is because i was thinking you can divide any number for example you divide 216 by 3 you get the quotient 72. But you can make unlimited number of combinations like that.
I don't know what in question itself gave you the clue to divide 72 by 18
Oh, I guess the misunderstanding comes from the word quotient.
The quotient of 72 and 18, by definition is what remains after you divide 72 by 18.
Your confusion is in thinking that 72 is the quotient, when in fact it is 4. Remember, it asks for "the quotient of", not stating "the quotient is"
