As you venture further into Infinity, keep your mind open to the peculiarities it brings to the mathematical table.

Basic properties of Infinity

  • Infinity is not a number, so it doesn’t follow the usual arithmetic rules. That is why you should think of it more like an idea or a state of being unlimited.
  • There’s no such thing as reaching Infinity, but you can always move toward it. Imagine always being on a path that keeps going; that’s how you should visualize approaching Infinity.
  • Infinite sets can come in different sizes, believe it or not. For example, there are more real numbers between 0 and 1 than whole numbers. Mind-boggling.
  • Remember, with Infinity, you cannot add, subtract, multiply, or divide like regular numbers. The rules change in the land of the limitless.

Operations with Infinity

  • Adding or subtracting a finite number from Infinity still leaves you with Infinity. It’s like adding a drop of water to the ocean!
  • Multiplying a positive number by Infinity also results in Infinity, just a bigger version—if that’s even conceivable.
  • Dividing a number by Infinity is like sharing a pizza among an infinite number of friends; each person gets an infinitesimally small piece, practically zero.
  • But be careful: some processes need to be more well-defined, like dividing Infinity by Infinity or subtracting Infinity from Infinity. Even scientists are cautious with these situations because they are like puzzles.

You’ll find Infinity is manageable with each property and rule you learn. Seeing how it plays by its own rules can be pretty thrilling. Keep these properties in mind; they will make your journey through mathematics much smoother and more enthralling.
