Answer

The missing value is -2.

Solution

We are given the equation:   6 = □ - (-8) Subtracting a negative number is the same as adding its positive, so the equation becomes:   6 = □ + 8 To solve for the missing value (the □), subtract 8 from both sides:   □ = 6 - 8 Thus:   □ = -2 So, the missing value is -2.

To solve the equation \( 6 = \square - (-8) \), we can simplify it by recognizing that subtracting a negative is the same as adding a positive. Therefore, the equation can be rewritten as \( 6 = \square + 8 \). To isolate the missing value, we subtract 8 from both sides: \[ \square = 6 - 8 \] \[ \square = -2 \] So the missing value is \(-2\). Visualizing this on a number line, if you start at \(-8\) and add \(6\), you would move \(6\) units to the right, landing at \(-2\). It’s a great reminder of how useful a number line can be for visualizing operations! Also, remember to keep track of your negatives! A common pitfall is forgetting that subtracting a negative is like adding. Just stay aware of the signs, and you’ll solve these problems like a pro!
