Key Concepts: Let’s Review!
Addition & Subtraction Properties
Propiedad de la suma de la igualdad
Todo lo que se agregue a un lado del
signo igual debe agregarse al otro
lado.
Propiedad de resta de la igualdad
Lo que se resta de un lado del signo
igual debe restarse del otro lado.

Key Concepts: Let’s Review!
Multiplication & Division Properties
Propiedad de multiplicación de la igualdad
Lo que sea que se multiplique en un
lado del signo igual debe multiplicarse
en el otro.
División Propiedad de la Igualdad
Todo lo que se divide en un lado del
signo igual debe dividirse en el otro.
