I am doing some light reading in the 2018 IECC https://codes.iccsafe.org/content/IECC2018P3/chapter4reresidentialenergyefficiency
Does anyone know what this part of Table 405.5.2(1) means?
I keep coming up with millions of Btu/day for a 1,000 square foot home. That can't be right...

forgot what that's called .............order of...........something0

I have to admit that the way it's presented isn't perfectly clear... @STEVEusaPA 's parentheses are correct  but it would be better if the publisher had put them in in the beginning, because @Zman 's interpretation isn't actually incorrect, considering just the way it's written, either.Br.

Thanks @STEVEusaPA
I guess you need to go to the IMC before they will trust you with 8th grade algebra order of operations"If you can't explain it simply, you don't understand it well enough"

I came up with 54,600 for my house. Which works out to be 2,277 btu's per hour.Interestingly, the formula assumes all the bedrooms are occupied to get that reading. That would have to be something to factor in if you were trying to get a very accurate heat loss of the house.

I had an "AHA" moment as soon as @STEVEusaPA pointed it out. The class where I learned order of operations was more than a few years agoLuckyDog said:Hey, at least he knew enough to know something was wrong....

I wonder how the kids solve that equation with the new style math?
