Combining two or more elements forms composite chemical mixtures. In some cases, if you change the order in which you mix two chemicals, it can produce very different results.
A composite function is made by combining two functions. If you are buying a $60 shirt and there is a 50% off sale and you have a $10 coupon, does it make a difference which discount is applied first? If so, which order results in a lower price?
