What is the definition of Calculators Macabre?

Let's break down this morbidly marvelous word: 'Calculators macabre' is a playful fusion of the mundane (calculator) and the macabre (something related to death or mementos). It's like describing a vintage calculator as if it's a graveyard of numbers, or a haunted abacus that just wants to tell ghost stories about forgotten digits. It's the term for a calculator that somehow manages to make you feel like you're staring into the abyss of mathematics, yet somehow, it's still making calculations.

Here's an unsettling example sentence: "As the old clock tower creaked ominously in the dead of night, I decided to sharpen my trusty calculator macabre, hoping to find out if my bad luck was just a number."
