고수님들 이식중 합산을 얻을 수 있을까요?

이 것은 각각 wr_35, wr_36 ~ wr_75, wr_76 에 두값이 곱한 것을 보여주는 5개의 식인데요
이것을 전부 합산한 한개의 결과를 보여줄 수 가 있나요?
<p id="result1"></p> =이것은 숨기고싶고 위에 5개의 식을 전부 더한 것만 보이고싶습니다.
ㅜ.ㅜ

<p id="result1"></p> 요소는 display: none; 스타일을 가지도록 변경하여 숨김 처리. 계산 결과를 누적하여 합산한 값을 sumResult라는 새로운 <p> 요소에 표시하도록 추가. 5개의 계산 결과는 각각의 <p> 요소에 표시되고, 전체 합산 결과는 sumResult 요소에 표시.
이렇게 하면 원하시는 결과값을 얻을 수 있지 않을까 생각합니다
감사합니다.

Php에서 하시면 더 수월할 듯합니다.
