Answer :
To solve the expression [tex]\(139 - (-30)\)[/tex], we need to understand how to handle subtraction with negative numbers.
1. Identify the Expression: We start with [tex]\(139 - (-30)\)[/tex].
2. Understand Negative Subtraction: When you subtract a negative number, it's the same as adding its positive equivalent. This is due to the rules of arithmetic, where subtracting a negative is equivalent to addition.
3. Convert the Expression: Change the expression [tex]\(139 - (-30)\)[/tex] into an addition problem by converting the double negatives:
- Rewrite [tex]\(139 - (-30)\)[/tex] as [tex]\(139 + 30\)[/tex].
4. Perform the Addition: Now, simply add:
- [tex]\(139 + 30 = 169\)[/tex].
Therefore, the distance represented by the expression [tex]\(139 - (-30)\)[/tex] is 169.
