In order to evaluate a definite integral first find the indefinite integral. Then subtract the integral evaluated at the bottom number (usually the left endpoint) from the integral evaluated at the top number (usually the right endpoint).
For example, if I wanted the integral of x from 1 to 2 (written with 1 on the bottom and 2 on the top) I would first evaluate the integral:
the integral of x is (x^2)/2
Then I would subtract the integral evaluated at 1 from the integral evaluated at 2:
(2^2)/2-(1^2)/2 = 2-1/2 =3/2.

What are some real life applications of indefinite integrals?
One of the major applications of indefinite integrals is to calculate definite integrals. If you can't find the indefinite integral (or "antiderivative") of a function, some sort of numerical method has to be used to calculate the definite integral. This might be seen as clumsy and inelegant, but it is often the only way to solve such a problem.Definite integrals, in turn, are used to calculate areas, volumes, work, and many other physical quantities that can be expressed as the area under a curve.

What are real world applications of integrals?
Most likely, you will not be doing integrals as part of your daily life, but knowing how integrals work, can help you understand how some things work. Foir example, the interest earned on an interest bearing account (like a savings account) when compounded daily, is close to the value for 'continuous compounding'. The rate curve represents the interest earned at a particular time, and the area under the curve (the integral of the function) represents the total accumulated interest.
What Is The Importance Of Limits And Continuity?
Those are among the most fundamental concepts in calculus; they are used to define derivatives and integrals.
