To find the additive inverse of a number, we simply change its sign.
The additive inverse of -2445 is 2445.
The additive inverse of -6710 is 6710.
Thus, -2445 - 6710 can be rewritten as 2445 + 6710.
Adding these two numbers gives us 9155.
Therefore, the correct answer is 9155.

To determine the distance between two numbers on a number line, we subtract the smaller number from the larger number and take the absolute value of the result.
In this case, 6.5 is the larger number and -7.2 is the smaller number.
6.5 - (-7.2) = 6.5 + 7.2 = 13.7
Taking the absolute value of 13.7 gives us the distance between the two numbers.
Therefore, the correct answer is 13.7.

Subtracting -8 from -6 means adding the opposite of -8. The opposite of -8 is 8, so the expression becomes -6 + 8.
-6 + 8 = 2
Therefore, the correct answer is 2.
To find the sum of -2445 and -6710 using the additive inverse, you need to add the two numbers together.
-2445 + (-6710)
When adding two negative numbers, you can simply add their absolute values and include the negative sign in the sum.
2445 + 6710 = 9155
Since both numbers are negative, the sum will also be negative.
So, the answer is -9155.
To find the sum of two numbers using additive inverse, you need to change the sign of the second number and then add it to the first number.
In this case, the first number is -2445 and the second number is -6710.
To find the sum, we need to change the sign of -6710. The additive inverse of -6710 is 6710.
Now, we can add -2445 and 6710:
-2445 + 6710 = 4265
Therefore, the answer is 4265.
