문제

덧셈, 뺄셈, 곱셈, 나눗셈을 할 수 있는 계산기 프로그램을 만드시오.

입력

입력의 각 줄에는 숫자와 +, -, *, /, =중 하나가 교대로 주어진다. 첫 번째 줄은 수이다. 연산자의 우선 순위는 생각하지 않으며, 입력 순서대로 계산을 하고, =가 주어지면, 그때까지의 결과를 출력한다. 주어지는 수는 108 이하의 양의 정수이다. 계산 중 결과는 0 또는 음수가 될 수 있지만, -108 ~ 108 범위를 넘지는 않는다. 또, 나눗셈에서 소수점은 버린다. 따라서, 100/3*3 = 99이다.

피제수가 음수일 때 나눗셈을 하는 경우는 입력으로 주어지지 않는다.

출력

첫째 줄에 계산 결과를 출력한다.
