Ok, but I’m not that good at Math. What should I do?

It is all about practicing! Imagine a scenario where the customer purchases a $17,89 product and gives you $20. Your computer is a bit slow, and you don’t want to take long to make the change. In this case, making the correct change requires a specific ability in math, right? No, it’s not really right! Do not worry if mental calculation is not for you. There is always a way! You can build a system of simple counting. For example, the purchase value is always your starting point. In this case, all you have to do is to count from 17,89 to 20,00, and you will make the right change, $2.11! Did you get it? No? No problem! Click on the link below, and I’m sure you will understand the “system.” The rest is all about practicing and training!
