여러분은 어떻게 생각하시나요?

48/2(9+3)=?

(컴퓨터에 응처럼 생긴 나눗셈 기호가 없어 /로 대체합니다. 이 컴은 컨씨 컨브이가 잘 안돼서...)

(1)2

(2)288

    혼합계산이면 288이라고 생각합니다.

      괄호가 없기 때문에 앞에서 차례대로 계산해야 할 것 같습니다

    전 항상 괄호가 먼저라고 생각합니다

    아, 말씀드리자면,이 문제의 논쟁은

    " 2(9+3)을 한 항으로 계산하는가 아니면 곱셈 기호가 생략되어있을 뿐이므로 차례대로 계산하는가"

    입니다.

      중학교에서는 하나의 항으로 생각하지만 초등학교 에서는 혼합계산으로 하죠...
      (아마도...)
