Maths and Numeracy A Presentation by Mitchell Welham And Ramsay Terry The Problem…. Steps to the Formula We firstly determine a formula through trial and error. From this we will be able to determine a specific formula in which for this task to work successfully. Example 1 Steps to the Formula Example 2 This example uses 5 by 3 giving us a total of 15 dots. Steps to the Formula Example 3 Again we are using an even number of dots. 5 by 8 gives us 40 dots. Can You See A Pattern? Have you noticed that when we use An Even number of dots, we can match them all up using varying patterns. An Odd number of dots, we cannot match them all up even using varying patterns. The Formula! So we need all dots in the area to be an even number for this problem to work. An Even number times an even number always equals an even number. An even number times an odd number always equals an even number. An Odd number times an Odd number always equals an odd number. The Formula! Vertical Lines Horizontal Lines Patterns Even by Even = Works using either a mixture of horizontal and vertical lines or using just horizontal and vertical lines. Even by Odd = Works using either a mixture of horizontal and vertical lines or using just horizontal and vertical lines. Odd by Odd = Always one left over (using a mixture of vertical and horizontal lines) Note that patterns do not depend on whether the horizontal or vertical lines of the area are divisible by 2 (except in an odd by odd situation). The patterns depend on the person making their desired pattern. They can make a pattern flow or make it random to fit. A lot of the time when using a mixture of vertical and horizontal lines, it requires trial and error to find patterns that fit accordingly. Our Problem as a Physical Application * Dots, dots and more dots. This may look like your average game of boxes but we assure you, it is not. So how do you complete a set of dots using only one line per each dot. First we must formulate …A FORMU
