Finding error in moment diagram calculation for beam

[musicmar]

Homework Statement

This would be really difficult to type, so I've attached the given problem and my work. I think it is legible for the most part, but let me know if you have problems reading something.

The Attempt at a Solution

My shear diagram worked nicely. I've run into a problem with the moment diagram. After I integrated the diagonal line function to get the area under the shear curve, I should have to add 24 kN to get back to 0, but from my previous work, I was at -36.

Any help in finding my mistake would be appreciated.

Thank you!
