Integral calculus result not identical?

Above, I've written down the calculation as I wrote it down in school. When I entered it into the calculator, I got the result. But when I try to calculate it without a calculator, I don't get the same result. Why is that? Which of these is correct?

You simply ignored the integral (or not integrated at all). It is intended to use only 4 and 0 in the function to be integrated (discharge).

You only have to determine the root function and then insert 4 and 0 into the root function, not into the derivation.

│(43 / 3) – 2 * 42│ = │-32 / 3│= 32 / 3

Hm, you forgot to integrate/redirect the function.
