Final answer:
The difference of -11 and -7 is calculated by adding the negative numbers together, resulting in -18.
Step-by-step explanation:
The difference of -11 and -7 requires understanding how to subtract integers. When subtracting a negative number, it is equivalent to adding its positive counterpart. So, the expression "-11 - 7" can be thought of as "-11 + (-7)", in which you add the negative numbers together.
So here's how you calculate it:
- Start with the first number: -11.
- Since you're subtracting 7, you need to add its negative equivalent: -7.
- Combine -11 and -7 to get -18.
Thus, the difference of -11 and -7 is -18.
Another example for clarity: If you subtract -6 from 2, which is written as 2-(-6), you actually add 6 to 2, giving you a result of 8.
