Question

Using properties of multiplication, find $56\times (-19)+56\times (-1)$

Answer 1

Given, $56\times (-19)+56\times (-1)$

Now, by using the distributive property

$$\begin{gathered} 56\times (-19)+56\times (-1)=56\times \left[(-19)+(-1)\right] \\ =56\times \left[-19-1\right] \\ =56\times (-20) \\ =-1120 \end{gathered}$$

Hence, the required value is $-1120$
