Step 1: Start by adding or subtracting the numbers from left to right, maintaining the proper signs.

-28 + (-44) = -72
Now the expression becomes:
-72 + 17 + 31 + (-94)

Step 2: Continue to evaluate the remaining numbers from left to right.

-72 + 17 = -55
-55 + 31 = -24
-24 + (-94) = -118

Therefore, the simplified form of the expression -28 + (-44) + 17 + 31 + (-94) is -118.
