We know from high school physics that s, the distance traveled by a car in t seconds can be determined using the following equation:

s = ut + 0.5at2

where u is the initial velocity and a is the acceleration of the car.

Now you are task is to find the value of s given u, a and t.

Input

3 double variables in a line denoting u, a, t respectively.

Output

The value of s, printed two digits after the decimal point.

Sample

Input	Output
10.00 2.20 5.53	88.94

Solution

#include<stdio.h>
int main()
{
    double u,a,t,s;
    scanf("%lf%lf%lf",&u,&a,&t);
    s=(u*t)+(0.5*a*(t*t));
    printf("%.2lf\n",s);
    return 0;
}
