ELI5: Explain Like I'm 5

Strictly singular operator

Okay, so imagine you have a bunch of Legos that you want to build into something cool. You can put the Legos together in different ways to make different things, right? But some of the Legos are special - they're called strictly singular Legos.

These strictly singular Legos are like the rockstars of the Lego world - they're super unique and rare, and when you add them to your building, they make it really special. But they're also a bit tricky. You can't just stick a bunch of them together and hope they work - you have to be really careful about the way you use them.

An operator is kind of like a Lego builder - it takes different inputs (like numbers or functions) and puts them together in different ways to make something new. A strictly singular operator is like a builder who is really good at using those special Legos. It can take those unique pieces and use them in a way that makes the new thing it builds even better.

But just like with the Legos, you have to be careful when you use a strictly singular operator. It's easy to mess up and use the special pieces in the wrong way. But when you get it right, the result can be really amazing.
