Sometimes I nearly need an equation or formula to work out exactly what is in a product because of the way it is labelled. It may be labelled per 100 g and the product may be 20 g or it may be labelled per 20 g and the product may be 100 g. At times, someone would need to have a degree in mathematics to figure it out.
