I’m not saying 2+2=5. I could probably make a case for it, but I might have to think about it a few minutes.So, you’re saying 2 + 2 = 5 or are you dancing around the issue?
I am saying that 2+2=4 is not objectively true, even in mathematics. In third grade math for most kids, it is objectively true given the small universe of mathematics to which kids are typically exposed. For a person who has accomplished even high school algebra, if they were good in math they would know there are cases where 2+2 is something other than 4, but most people don’t realize it because they never gain a practical use of it. For me, I have a master’s degree in electrical engineering and used to teach math, and I have had many occasion to use mathematics where 2+2 is not equal to 4.
The reason I bring this up is that 2+2=4 is always, objectively true is an example of a false cliche that shows an assumed limitation that both parties to the conversation might not have. If you say, “in all of mathematics this statement is objectively true,” then I have to say you are wrong and presumptuous, and your own lack in mathematical training causes you to make that limited vision statement as if were true for everybody but yourself.
That is another reason that I do not blame and judge people who don’t understand these lessons. They were not taught, in mathematics or any other place, how to envision there might be truths beyond what we personally know. In short, they’ve been taught what to think and say, rather than how to think.
That is why Christ talked in parables. People did not have the language or the disposition of heart (old wineskins) to understand the messages directly, so He had to plant seeds that would grow.
The last time I demonstrated two different contexts in which 2+2 is not 4, (actually I think it involved 1+1=2) others (on this forum btw) cried “no fair” because I didn’t heed certain limiting assumptions that I neither made nor anybody stated.
In short, for children’s mathematics, 2+2=5 is incorrect, and yes I would mark that wrong.
If you want some practice at grade school math, I can show you some tests I’ve written and have been used thousands of times by a couple hundred grade school students. They are automated flashcards, timed, and dedicated to my fifth grade math teacher Sister Geraldine Marie. They are very small DOS programs, under 100k, that can be downloaded and run (not installed) in any directory and they store results of completed tests in a file. I offer them to forum members and any friends as freeware.
You can use addsub.exe to avoid negative numbers, or use addsubn.exe to practice adding and subtracting with negative numbers galore. You can train your kids on them and they will be the winners in math contests.
Yes, addsub.exe and adsubn.exe both would regard “5” as an incorrect answer to the problem “2+2”
edit>> sorry I forgot to say where to find these programs:
The programs can be found at math.wordsfree.org/
There are several programs there, enough to challenge anybody – try one of the fraction programs; they will drive you mad being timed while adding things in your head (or using scratch paper which is not cheating but adds overhead) such as -2 3/5 + 1 2/3
