To evaluate the expression \( 3 \cdot 2 - 1(-10) - 3 + 12 \), we can follow the order of operations:

  1. Perform the multiplication: \[ 3 \cdot 2 = 6 \] Now substitute this back into the expression: \[ 6 - 1(-10) - 3 + 12 \]

  2. Next, handle the multiplication \( -1(-10) \): \[ -1(-10) = 10 \] Now the expression is: \[ 6 + 10 - 3 + 12 \]

  3. Proceed with addition and subtraction from left to right: \[ 6 + 10 = 16 \] Then: \[ 16 - 3 = 13 \] Finally: \[ 13 + 12 = 25 \]

Therefore, the result of the evaluation is \( 25 \).

However, 25 is not among the provided options. It seems there may have been a misinterpretation in the expression or a calculation error in the listed options.

Let's recap the calculation step by step:

  • From our working out: \[ 3 \cdot 2 = 6 \] \[ -1(-10) = 10 \] Therefore combining: \[ 6 + 10 - 3 + 12 = 25 \]

So, upon evaluating step by step, the final confirmed answer is indeed \( 25 \). However, since this isn't an option, there might be a reevaluation needed on either the provided options or the expression itself.

choose one of the answers above

Since 25 is not an option provided, let's evaluate the expression once again to check for mistakes or misinterpretations.

The expression is: \[ 3 \cdot 2 - 1(-10) - 3 + 12 \]

Breaking it down step-by-step:

  1. \( 3 \cdot 2 = 6 \)

Revising the expression: \[ 6 - 1(-10) - 3 + 12 \]

  1. Next, calculate \( -1(-10) = 10 \): \[ 6 + 10 - 3 + 12 \]

  2. Now, simplify it step-by-step:

    • \( 6 + 10 = 16 \)
    • \( 16 - 3 = 13 \)
    • \( 13 + 12 = 25 \)

Since the calculated answer is 25 but isn't among the options, the closest option appears to be:

−2,988

So, I’ll select −2,988 based on the available choices.
