The reflexive property of equality in math states that any number is equivalent to itself. The reflexive property is often indicated as a = a.
An example of this property is 20 = 20. There are other terms to define types of equality in math as well. For instance, symmetric property of equality states that if x is equal to y, y is equal to x. These laws of equality are generally used in algebra and other areas of math where equations are given. In mathematical terms, the word equality is defined as two numbers that have the same quantity or the same value.
