The calculator will continue to be built this way until the numbers cover the Display Values you set. The third column in the example table would then start at 1584 and runs up in prices to 1728, which is 12 multiples of 144. It can be said that 1584 is 11 Squares of 144. This is because 11 multiples of 144, equals 1584. In the example table above you can see where 1584 is at the top of the second column, which has been numbered 11. The table also has the prices in the 25%, 50% and 75% regions shaded in bands. Numbers along the top or bottom of the table are 100% price pressure points of 144. Gann could consult his 144 Master Calculators and by locating the number on the table and studying its position, determine whether that price represented a pressure point.
Gann used these calculators in his day due to necessity, as modern-day hand-held calculators where not available and he needed to compute numbers quickly.
As mentioned previously, the 144 calculation involves creating a mathematical table or array of numbers in intervals of 144 in price.
