Question

Use the additive inverse to find −1223−(−856)
. Write the answer as a mixed number.

Answer 1

To solve the expression \(-1223 - (-856)\) using the additive inverse, we can rewrite it as follows:

\[
-1223 + 856
\]

Now, we can do the addition:

1. Since \(-1223\) is negative and \(856\) is positive, we can think of this as finding the difference between their absolute values.

2. First, we calculate the absolute values:

\[
| -1223 | = 1223
\]
\[
| 856 | = 856
\]

3. Now, we subtract the smaller absolute value from the larger one:

\[
1223 - 856 = 367
\]

4. Since \(-1223\) has a larger absolute value, the result will be negative:

\[
-1223 + 856 = -367
\]

Thus, the answer is \(-367\), which can also be represented as a mixed number. Since \(-367\) is a whole number and cannot be expressed as a mixed number with a proper fraction, we can just write:

\[
-367
\]

Hence, the final answer is:

\[
\boxed{-367}
\]
