Numbers also have different forms!
How do the look like?
What are the different forms of numbers?
In this standard of math, I have used the "Form" Key to see how numbers are expressed in different forms.
The functions of numbers are many. We use them to count, know the size, value, height, weight, temperature, cost and many more things. The connection between numbers and how they change from one form to another is an interesting world to explore!

Is when a big number can be balanced when many small numbers come together. E.G 420 400+20 100+100+100+100+20 500-80 210 x 2 840/2
