Question

Find the product of the sum of -10 and -3 and the difference between -10 and 3

Answer 1

all you need to do is convert the words into math terms and then, operate

Step 1

Let

the product= the multiplicaion = *

difference = a substaction

Step 2

replace

the sum of 10 and -3=

`\begin{gathered} 10+(-3) \\ 10+3 \end{gathered}`

the difference between -10 and 3

`\begin{gathered} -10-3 \\ -10-3 \end{gathered}`

Now, the product

`\begin{gathered} (10+3)\cdot(-10-3) \\ \end{gathered}`

eliminate the parenthesis

`\begin{gathered} (10+3)\cdot(-10-3) \\ 13\cdot-13 \end{gathered}`

make the multiplication

`\begin{gathered} 13\cdot-13 \\ -169 \end{gathered}`

so, the answer is -169
