Product notation Memes

The mathematical warrior has spoken! This meme beautifully captures the properties of empty products in mathematics. When you multiply zero numbers together (from i=1 to 0), you get 1 by definition - not zero as intuition might suggest. It's like showing up to a multiplication party where nobody brought any factors, yet somehow you end up with a value! Meanwhile, multiplying any set of numbers that includes a zero will give you zero (as shown in the first two equations). The climbing character perfectly represents the index "i" that "can only go up" from its starting value - exactly how mathematical notation works. Mathematicians didn't make these rules to torture students... but that's definitely a bonus feature.
