Change for the Better


Change for the Better -
A New, Quicker Way to Make Change with Cash (With no Carrying!)

Change for the Better Image

  • If you work with money at all, this booklet is for you.

  • If you ever spend money, this booklet is for you, too.

  • If you have children who plan to do either, this booklet is for them as well.

With the techniques described here, you will be able to calculate you change almost instantly. Anyone who works at a register should be required to know everything in here. It will save them from embarrassing mistakes, and from getting ripped-off by scam artists.

Here are techniques that will:

  • enable you to make change almost instantly, without using the "old way" - there is no carrying! The calculations are done from left to right, starting with the highest column, not the "chump-change."

  • help you understand a new, more effective way to do arithmetic

  • open your mind about math

  • impress your customers and employer, improve your tips, make you a more efficient worker, save you time

  • increase you personal pride in how well you do your job

  • help you from getting ripped-off

  • save your butt when the register is down.

This booklet is a godsend for waiters and waitresses, bartenders, ticket-takers, and other people who are too busy to get to the register to add up a sale.

Employers- Do you get frustrated with new employees who can't give change accurately? They are a reflection on you and your business. Help them and yourself by giving them a copy of this booklet.

Employees - Do you have customers who don't understand change, or are impressed with how good you have gotten with the help of this booklet? Why not recommend this booklet to them?

Customers - Fed up with knucklehead cashiers who can't add or subtract without a calculator? Or even with one? Recommend this booklet to them.

Parents - Give you children an advantage in the employment market by improving their confidence in their calculating skills. (It won't hurt them in math class, either!) This is the first booklet in a series of how to deal with money in daily life.

Learn these methods right away, and set yourself along the way to using major Math Mojo in your daily life!
