Pinwheel calculator
Have you ever seen a pinwheel? It's a fun toy that spins when you blow on it. Now imagine a pinwheel that has some numbers on it, like 0-9. This is called a pinwheel calculator.
When you want to do some math, you can spin the pinwheels to show the numbers you need. Let's say you want to add 25 and 36. First, you spin the pinwheel for the ones place to show 5 and 6. Then you spin the pinwheel for the tens place to show 2 and 3.
Now you have the numbers 5 and 6 in the ones place, and 2 and 3 in the tens place. You can add them up to get the answer: 61. Isn't that cool?
Pinwheel calculators are a fun way to do math and learn about numbers. They're also easy to use and don't need electricity like regular calculators. So next time you want to do some adding or subtracting, give a pinwheel calculator a try!
