Total Number Technique is (TNT) was used to remember numbers. Because the right brain does not know the number or word, it needs to create stories in order to recognize the right brain. For example, you have to remember 007 digits. You can turn it into a story like James Bond (007).
However, not all combinations of numbers are numbers that are known as above. For that, you can make the story his own by turning it into code that can be accepted by the right brain that is in code form or sound. You can change the numbers into code form or sound like the following :
0 = Ball
1 = Pillar
2 = Duck
3 = Ear
4 = Chair
5 = Letter S
6 = Pregnant
7 = Hoe
8 = Glasses
9 = Racquet
