In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number. For example, 32x1=32.   Sal Khan video https://cdn.kastatic.org/googleusercontent/a2avkWV_Lhnci8VwoKRpIle3Y1c5JuE8hgc4Bireqa2GH-3wDZYE0Ly90k1USprvCnngfN4od3DhRC3UX85_O7C7 Identity property of 1 The identity property of 1 says that any number multiplied by 1 keeps its identity.
