Answer :
To determine what number should be added to get the sum of -1, let's follow these steps:
1. Identify the target sum:
- The target sum we want to achieve is -1.
2. Determine the initial value:
- Let's assume the initial value is zero (0).
3. Formulate the equation:
- We need to find a number \( x \) that, when added to the initial value (which is zero), results in the target sum of -1. This can be expressed as:
[tex]\[ \text{initial value} + x = \text{target sum} \][/tex]
Substituting the known values:
[tex]\[ 0 + x = -1 \][/tex]
4. Solve for \( x \):
- To solve for \( x \), we rearrange the equation:
[tex]\[ x = \text{target sum} - \text{initial value} \][/tex]
Since the initial value is 0 and the target sum is -1:
[tex]\[ x = -1 - 0 \][/tex]
[tex]\[ x = -1 \][/tex]
So, the number that should be added to the initial value of 0 to get the sum of -1 is -1. Therefore, the final sum is -1.
- Target Sum: -1
- Initial Value: 0
- Number to Add: -1
Thus, the numbers involved are:
[tex]\[ (-1, 0, -1) \][/tex]
