To find the additive inverse of a number, we change the sign of the number.
The additive inverse of -856 is 856.
Now we can subtract -856 from -1223:
-1223 - (-856) = -1223 + 856
To add these two numbers, we align them vertically and add the corresponding place values:
```
-1223
+ 856
-------
```
Starting from the rightmost column, we have:
3 + 6 = 9
2 + 5 = 7
2 + 8 = 10
Write down the 0 and carry over the 1:
1 + 1 = 2
Adding all the column values, we have:
```
-1223
+ 856
-------
367
```
Therefore, -1223 - (-856) = 367.
The answer as a mixed number is: 367
Use the additive inverse to find −1223−(−856). Write the answer as a mixed number.(1 point)
