If you have 2 apples, and then I give you 2 more, you don’t suddenly have 5 apples because we all decided 2+2=5.
No, but some types of addition follow their own rules.
Sometimes 1+1 is 2. One Apple plus one Apple is two apples.
Sometimes 1+1 is 1. Two true statements joined together in conjunction are true.
Sometimes 1+1 is 0. Two 180° rotations is the same as if you didn’t rotate the thing at all.
If you don’t define what kind of addition you’re talking about, then it’s not precise enough to talk through what is or isn’t true.
Phosphates were banned in dishwasher detergents in 2011, so most of the name brand companies switched to enzyme-based cleaners that use amylase and protease, which dissolve starches and proteins, respectively. And then some traditional detergent, which allows oil and water to mix, washes it all away.
The nature of the enzymes are that as soon as they’ve broken up the starch or protein, they survive the reaction and can happily move onto the next starch or protein molecule. So if they’re overactive, without enough targets, then any portion of the dishes that are sensitive to that particular cleaner is going to get a higher “dose” of that cleaner working specifically at it.
