Forgetting to carry the 1 while multiplying two numbers gets you a wrong answer within the same order of magnitude as the right answer Multiplying the *wrong two numbers* is a far more consequential mistake

(This came up on Square One TV when I was a kid Months typically have four seven-day weeks, plus a few days extra It is very tempting to round down and just say "one month = four weeks" But if you do that for the whole year, you've cheated someone out of 4 weeks out of 52)

(That particular example, even though you'd think it's a fucking obvious one, is one that's been used to fuck over uneducated people in the wild before Hence you always count the number of weeks in a year by dividing 365 / 7 = 52 plus a day, not by adding up the months)

Imagine opening up a street market with a scale like that.

Again, all scales are like that

1)This whole conversation has grown wildly out of control. The original point of 2+2=5 was to draw attention to subjectivism being introduced into mathematics.
-
2)Meaning that - in the particular context in which we commonly understand math (the axioms, scales, etc that are used in everyday math) 2+2 does not equal 5. Objectively speaking, in that particular context, 2+2 does not equal 5.

No it's not. If you describe that phenomenon as 2+2=5, I wouldn't have a clue as to what you mean. If you did the scale overstates weight, I would.

What's interesting is to describe the inaccuracy of a scale by 2+2=5 and think that equation is meaningful beyond expressing a machine is flawed in its principle function.
