A binary operation is one which takes two numbers and combines them into one. +,-,* and / are all binary operations.
If you start with 4 numbers and apply one binary opeartion (to two of the numbers) you are left with three. After two binary operations you are left with two numbers and after three binary operations you are left with only one number. You cannot, therefore, carry out the fourth binary operation if you start with four numbers.
