Question

evaluate the expression.
2 × (8 - -1) - 6

Explanation:

Step1: Simplify the subtraction inside the parentheses

We know that subtracting a negative number is the same as adding its positive counterpart. So, \(8 - (-1)=8 + 1 = 9\)

Step2: Multiply the result by 2

Now we have \(2\times9\). Calculating this, we get \(2\times9 = 18\)

Step3: Subtract 6 from the product

We take the result from step 2, which is 18, and subtract 6: \(18-6 = 12\)

Answer:

12
