If we want to go from 2^2 to 2^3 we simply multiply by 2.

2^2 = 4 -> 4×2 = 8 = 2^3

But now let’s try going backwards. If we want to go from 2^3 to 2^2, since we multiplied going forwards we will divide going backwards.

2^3 = 8 -> 8/2 = 4 = 2^2

Now let’s keep applying that logic:

2^3 = 8

2^2 = 4 (8/2)

2^1 = 2 (4/2)

2^0 =1 (2/2)

And we can keep going:

2^-1= 0.5 (1/2)

2^-2 = 0.25 (0.5/2)

And so on.

Works with every number, try it out!

Edit: this is probably too late of an edit but since a lot of people are mentioning 0. I just want to say this is not an explanation of how exponents work, but rather a proof to show why x^0 = 1, given x is an integer and not 0.

If you want an explanation of how exponents work, since all our teachers did a terrible job, check out this [article](https://betterexplained.com/articles/understanding-exponents-why-does-00-1/) I found. I thought it did a great job at explaining the how.

Also please guys I don’t care for internet points, instead of giving me an award buy yourself a chocolate bar (idk how much awards cost? Does it cost the same as a chocolate bar? 😅)
