Number bases Memes

The mathematical crime scene you're witnessing is what happens when someone writes π as a string of 3's with different subscripts. Those subscripts? They're actually different number bases. So that "3" with a subscript "4" is actually 3 in base 4, which equals 3 in decimal. But "3" with subscript "16" is 3 in hexadecimal, which equals 3 in decimal too. Engineers, notorious for approximating π as just 3, are celebrating this mathematical sleight of hand that technically makes their approximation correct. Mathematicians are currently filing restraining orders against whoever created this.
