Lambda expressions are how anonymous functions are created. In this article and code examples, we will see how to implement lambdas in C#. Lambda expressions are anonymous functions that contain expressions or sequences of operators. All lambda expressions use the lambda operator =>, which can be read as “goes to” or “becomes”.

Two numbers r and s sum up to 1 exactly when the average of the two numbers is \frac{1}{2}*1 = \frac{1}{2}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. Two numbers r and s sum up to -3 exactly when the average of the two numbers is \frac{1}{2}*-3 = -\frac{3}{2}.
