Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

How do you explain a made up number system for school project?
Step 1: Create your number system. You can do this by using symbols to represent numbers. For example, the Romans used what we refer to as "Roman Numerals." In their number system, I=1 II=2 III=3 IV=4 V=5, and more. So you could use like a smiley face for 1 or something, a frowny face for 2, and more.
Step 2: Figure out how multi-digit numbers will be written. You can't have a different symbol for every number! First of all, it's impossible, and second of all, no one can remember zillions of different symbols to represent numbers! The Romans wrote numbers like 52 as LII (L=50, II=2). I would recommend doing something like our number system, where there are 10 different numerals (0,1,2,3,4,5,6,7,8,9) and when they are in different spots in a multi-digit number, they equal a different value.
Step 3: Figure out how you're going to do different operations (addition, subtraction, multiplication, division, etc.) I'm going to make this simple, use our numerical operation strategies. (the same way we add, subtract, multiply, divide, etc.)
Step 4: Explain!
Step 4.1: Start by making a chart or table to show what made-up numbers equal our numerals.
Step 4.2: Answer this question: How do you write multi-digit numbers in your number system?
Step 4.3: Answer this question: How do you do different operations with your number system?
