Question

Find the value of 6 x (4 + 8) ÷ 4 - 7.

Answer 1

We have the following operation:

`6\text{ x \lparen4+8\rparen}/4-7`

And we need to find the result for that operation.

1. To find that, we need to use the PEMDAS order of operations, and the order of performing each of them is as follows:

• Parentheses

,

• Exponentials

,

• Multiplications

,

• Divisions

,

• Additions

,

• Subtractions

2. Then we can perform the operation as follows:

First: Parenthesis

`\begin{gathered} 6*(4+8)/4-7 \\ \\ 6*(12)/4-7 \end{gathered}`

3. Now, we have a multiplication:

`72/4-7`

4. Then, we have to perform the division, and, finally, the subtraction:

`18-7=11`

Therefore, in summary, we have that the result of the operation given above is 11.
