So you all laugh. But at the right level of math these are very important concepts in engineering.
2.49 + 2.49 does equal 5. That is why we spend the entire first-year of engineering to study significant digits. We would round to the accuracy of the measurement device and probably express the solution as 5.0 so others know the result was rounded. So 2+2 might equal 5, which is why it is so important not to round your work early and to keep track of units and not take numbers out of black-box models without understanding their origin.
There are similar concepts in high-level statistics.
This type of thing is what every journalist and keyboard warrior and even doctor is doing right now with the COVID data. Which why all the data and models are fucked.
The problem is this social justice faggot has probably never taken any math, took his examples out of some SJW textbook and is using it to teach racism to 10-year-olds.
I am saying that if you fuck up 2+2 by using bad data you get 4 when really it should be 5. It sounds dumb, but you have start somewhere.
Very few things in life are exact integer math. So with COVID everybody is obsessed with reporting it as an integer. Because that is all the average idiot can understand. People come in integer quantities correct?
So everybody reports that there are 2,000 cases per province and they add them up to get 20,000 cases. But in reality there is a certain probability distribution of false positives and it varies depending on the test used. And there is a certain probability distribution of false negatives. And the is a certain probability distribution that tests are getting lost or double recorded. etc etc
So you can't just add up 2+2+...+2=20. Because there may be as few as 10 or as many as 30 thousand depending on the stats.
That is the type of thinking that question is supposed to instill in a young child if tought properly.
Deeper into the thread, he uses a Wendy's 2 for $5 burger deal as an example of when 2+2=5.
