How mathematics is used in cake baking?

you would need basic math with ratiOS to figure how to evenly place the repetitive decorations pleasingly on the cake icing.. A cake decorator is just another form of an artist, they use colored icing instead of paint. Applying the repetitive decorations is usually starting at the points of a compass, and eyeballing it from there. The largest problem is keeping the icing colors mixed the same from batch to batch (ratio of icing to coloring).
