Hi, English isn’t my mother tongue so I was asking myself that question since I first encounted a w/… Back then I was like: “What tf does ‘w slash’ stand for?” And when I found out I was like “How, why, and is it any intuitive?” But I never dared to ask that until now
University shortcut. When you have to take notes on paper so damn fast, you develop techniques. Those techniques get shared around. That’s how it was explained to me.
Oh, OK. Thanks for your answer ^^
