public class 盐水的故事 {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner in = new Scanner(System.in);

int VUL = in.nextInt();

int D = in.nextInt();

int time = 0;

int sumVul = 0;

for (int i = 1; i <= VUL / 2; i++) {

if ((sumVul + i * D) < VUL) {

sumVul += i * D;

time = time + 1 + i;

} else if ((sumVul + i * D) == VUL) {

time = time + i;

break;

} else {

int yx = VUL - sumVul;

while (yx > 0) {

yx = yx - D;

time = time + 1;

}

break;

}

}

System.out.print(time);

}
