14056-(42103+14):3+(18710-18708)*45

To solve the expression, let's break it down step by step:

1. Firstly, perform the addition inside the parentheses: 42103 + 14 = 42117.

2. Next, subtract the result from the previous step (42117) from 14056: 14056 - 42117 = -28061.

3. Now, let's solve the expression inside the second pair of parentheses: 18710 - 18708 = 2.

4. Multiply the result from the previous step (2) by 45: 2 * 45 = 90.

5. Finally, divide the result from step 2 (-28061) by 3, and add the result from step 4 (90): (-28061 / 3) + 90.

Now let's calculate the final result:

-28061 / 3 = -9353.66667 (rounded to 5 decimal places). -9353.66667 + 90 = -9263.66667 (rounded to 5 decimal places).

Therefore, the final result is approximately -9263.66667.
