Question

I need a SIMPLE definition of the addition property of equality, subtraction property of equality, multiplication property of equality, and division property of equality.​

Answer 1

Addition property of equality: tells us that if we add the same quantity to both sides of an equation, then our equation remains the same.
Subtraction property of equality: tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
