버블몬은 음수를 매우 싫어한다.
식을 계산하던 도중 음수가 나오면 아주 슬퍼한다.
버블몬은 연산자 우선순위*를 무시하고 계산기처럼 연산한다.
아래 식들 중 버블몬이 계산하다가 슬퍼할 식을 모두 구하여라.
--------------------
*연산자 우선순위 란?
곱하기와 나누기가 더하기와 빼기보다 우선적으로 계산되며 괄호를 씌운 부분부터 연산하는 것을 말한다.
--------------------
1. 32-30*4-10+2500
2. 45+31*2-1500
3. 2*5-1*4-37
4. 45*2-85*130
5. 12*12-130+21*2
6. 5*50-240*10-150
