ELI5: Explain Like I'm 5

Subtractor

A subtractor is like a really cool magic machine that can take two numbers and help us figure out how much smaller one is compared to the other.

Imagine you have a bag of 5 apples and you give away 3 apples to your friend. Now, how many apples do you have left?

To figure this out, we use a subtractor machine. We tell the subtractor machine that we had 5 apples and we gave away 3 apples. The machine takes away the 3 apples from the original 5 apples and gives us the answer, which is 2 apples.

The subtractor machine is like a calculator but instead of adding numbers, it takes away numbers. It's a really helpful tool for doing math problems like figuring out how much money you have left after spending some or how much time you have left before a certain event.

Subtracting can be a bit tricky at first, but once you get the hang of it, it becomes super easy and fun!
