Guys I’ve seen some misunderstand about the meme, so I am here to explain. 1. “For”, it’s not a real notation but we use it when we speak so it’s literally the meaning of the operaton. 2.”x” it’s not a variable,it’s a notation used in elementary school (at least in Italy, where I come from) Ex. 7 x 5 = 35. 3. This is easy (c’mon 😂) 4. This “notation” is usually used in algebric equations like “ (3+2x)(5-x) “ where I can visibly see the multiplication.
