This is why fonts and kerning are so very important. But then again, the text in the boobs looks like it has extraneous spaces deliberately to look like that. There is a noticeable visual difference between 2! = 2 and 2 != 2 when spaced properly.
Can confirm. Am a programmer and my first thought was that mathematicians had recently come up with one of their wacky proofs that 2 does not equal 2, like how 1 is equal to 0.
Damnit. Got me. I’ve been a programmer for the better part of nearly 20 years but I was a math-heavy engineer first and I still freaking read that as “two-factorial”.
