Question

$(15\times -4)+(-6\times -1)-(-7\times 4)=$

• A. $0$
• B. $-26$
• C. $104$
• D. $-38$

Answer 1

The correct option is B $-26$

The given expression is $(15\times -4)+(-6\times -1)-(-7\times 4)$

$\bullet (15\times -4)$ describes the multiplication of a positive number $\left(15\right)$ with a negative number $(-4)$ which results in negative output, i.e., $-60$.

$\bullet (-6\times -1)$ describes the multiplication of a negative number $(-6)$ with a negative number $(-1)$ which results in positive output, i.e., $6$.

$\bullet (-7\times 4)$ describes the multiplication of a negative number $(-7)$ with a positive number $\left(4\right)$ which results in negative output, i.e., $-28$.

Hence,
$$\begin{array}{c}\begin{array}{cc}& (15\times -4)+(-6\times -1)-(-7\times 4)\\ & =(-60)+(+6)-(-28)\\ & =-60+6+28\\ & =-60+34\\ & =-26\end{array}\end{array}$$
