Yep it can be both
And also,
1.9+1.9=3.8
1.9≈2
3.8≈4
Therefore, 2+2=4

wrong because in that instance you are just making the real answer of 2+2 more difficultand who wants math to be difficult

Then 2+2=5 is also wrong because you can not just treat an approximate value and a precise one same -- It should be "roughly equal" so 2+2 can roughly be in (3, 5).

actually that makes sense you have convinced me
1+1=2
2+2=4
I saw a video, some teacher tried explaining to a kid that 2+2 is 4 not 22 and the school fired her for it. So they gave her her 2,000 pay + her 2,000 pay and she demanded 22,000
everyone here is wrong the answer is obviously 174.64, because 1+1=87.32
4 ha ha
