    What have you tried so far?

    Hint: Integrals represent the area between the curve y = f(x) and the x-axis.

    Re: Solving definite integral given values of other definite integrals?

    Thanks for the reply Dan.
    I understand areas between the x-axis and curves, but only between two x-values.
    To be completely honest, I have tried simple trial and error, and using a property of definite integrals, but I've been unsuccessful.
    The answer is 3, which leads me to believe I have to subtract 5, 3 and 1 from 12. I still do not understand why and it would be extremely appreciated if you could clarify it.

    10= (10- 7)+ (7- 2)- (4- 2)- (0- 4)
