Within the Bubblegum Machine, are several examples of more complex mathematical strategies. An example of one, is the use of scale factors and a centre of enlargement to alter the size of a specific shape. Once the original shape is placed on a grid, you are able to change the size of it by multiplying each side by the scale factor. Making the whole process more difficult, is the inclusion of a ‘centre of enlargement’ (a coordinate that you place on the grid). Every point of the shape is moved in relation to this point. You are able to ascertain whether the shape has altered correctly by ruling lines through each of the points.

Another example of a mathematical strategy evident in the Bubblegum Machine is the tessellating pattern that sits along the base. There are two types of tessellating patterns - regular and irregular. The example shown is the regular version. A tessellating pattern is unique, in that the shape can slide, reflect, flip or rotate onto itself. The example shown on this machine has been rotated and flipped (both clockwise and anti-clockwise), each time at a 90 degree angle.
