The 'Box' Technique

This is a technique used for questions where you have to find out how many things does one person has compared to others.

Simple Question:
Sally had 12 ducks. Bill has x3 more ducks than Sally. Jerome has 18 ducks less than Bill. 

S {12}
B {36} 12x3
J {18}  12x3-18

This is a really simple question - you do not need to use this technique for this.
When you get to harder questions, this is useful.

12 is one whole therefore counting as one 'box'.
12x3 is 3 boxes
12x3-18 is 3 boxes minus 18.

Easy and neat way to answer these questions.
