Question

How do you evaluate `9( - 7- 7\cdot 7)`?

Answer 1

See a solution process below:

Explanation:

Using the standard order of operations or PEDMAS, you first evaluate the expression within the Parenthesis. The first operation within the parenthesis is the Multiplication:

`9(-7 - color(red)(7) * color(red)(7)) => 9(-7 - 49)`

Next, execute the Subtraction operation within the parenthesis:

`color(red)(7)) => 9(color(red)(-7) - color(red)(49)) => color(red)(7)) => 9(-56)`

Now, complete the evaluation by execution the Multiplication operation:

`color(red)(9)(color(red)(-56)) => color(red)(9) xx color(red)(-56) => -504`
