I’ll admit it: I’ve always loved algebra. Geometry? Eh, not so much. But with algebra, you can literally solve anything, especially when baking. For example, take this question from ck12.org: How can we make enough chocolate chip cookies for an exact amount of people with only one recipe? Easy, use algebra. Or, this question from a text book word problem from algebra.com: How many trays of each type of muffins should the baker make to maximize his profit? Use linear algebra. Or, how to convert Celsius to Fahrenheit or the other way around (aaamath.com)? Create an algebraic formula.
But when cake cutting is involved, it involves more than simply cutting a slice from a whole. Will each piece be equal, or at least, perceived as equitable between the guests eating it? Will everyone be happy? Will the remaining pieces dry out? I look into how mathematics come into play when cutting a perfect cake slice, and reference two journals, Nature from 1906, and Notices from 2006, that try to solve just those questions.
It would be a delicious question to solve.
