I just saw a Scientific American article about the recent inclusion in Unicode of the
[Kaktovik Numerals](https://en.wikipedia.org/wiki/Kaktovik_numerals),
a base-20 counting system invented in 1990 by schoolchildren in northern Alaska.
Let's do some counting!
<div class="flex wrap counter" data-min="0" data-max="19">
<div>
<h3 class="justify-center">Apple-inator</h3>
<button class="add" data-amount="-1">- 🍏</button>
<button class="add" data-amount="+1">+ 🍏</button>
</div>
<div>
<h3 class="justify-center">Apples</h3>
<div class="apples"></div>
</div>
</div>
Seems pretty easy, right?
I had it group apples in rows, so it's easier to visually see how many apples you have.
Let's use 🍊 instead of 🍏🍏🍏🍏🍏,
to make it even easier to see how many rows we have.
<div class="flex wrap counter" data-min="0" data-max="19">
<div>
<h3 class="justify-center">Apple-inator</h3>
<button class="add" data-amount="-1">- 🍏</button>
<button class="add" data-amount="+1">+ 🍏</button>
</div>
<div>
<h3 class="justify-center">Fruit</h3>
<div class="fruit"></div>
</div>
<div>
<h3 class="justify-center">Apples</h3>
<div class="apples"></div>
</div>
</div>

<div class="flex wrap counter" data-min="0" data-max="19">
<div>
<h3 class="justify-center">Apple-inator</h3>
<button class="add" data-amount="-1">- 🍏</button>
<button class="add" data-amount="+1">+ 🍏</button>
</div>
<div>
<h3 class="justify-center">Kaktovik</h3>
<div class="kaktovik justify-left"></div>
</div>
<div>
<h3 class="justify-center">Fruit</h3>
<div class="fruit"></div>
</div>
<div>
<h3 class="justify-center">Apples</h3>
<div class="apples"></div>
</div>
<div>
<h3 class="justify-center">Arabic</h3>
<div class="arabic justify-right"></div>
</div>
</div>
Can you see how
the number of left-and-right lines is the number of complete rows of apples,
and the number of up-and-down lines is the number of apples left?
