Math

Math major: 2+2=4
Social science major: 2+2 is a social construct
Computer science major who's into infosec: 1=1
Computer: 2+2=4.000000000000000002

1=1 is important because it fundamentally asserting that 1's are replaceable common quantity markers, that no 1 is unique or positionally different(e.g. each of 1's in 1.11 has different meaning).
