# Review of Mathematical Principles and Applications in Food Processing

Chapter

## **Abstract**

Avariable is a quantity that can assume any value. In algebraic expressions, variables are represented by letters from the end of the alphabet. In physics and engineering, any letter of the alphabet and Greek letters are used as symbols for physical quantities. Any symbol may represent a variable if the value of the physical quantity it represents is not fixed in the statement of the problem. In an algebraic expression, the letters from the beginning of the alphabet often represent constants; that is, their values are fixed. Thus, in the expression ax = 2by, x and y represent variables and a and b are constants.
