What does the Reflexive property of equality states?

• If numbers are equal, they will still be equal if the order is changed. 
• A number is equal to itself. 
• If numbers are equal to the same number, then they are equal to each other.
• Subtracting the same number from both sides or an equation does not  change the equality of the equation.
