Hi everyone, what are some of the advantages and shortcomings of using Egyptian number system? In my opinion, Advantage: Using numeral hieroglyphs can visualize the process of addition and subtraction, make them easy to learn for beginners. Disadvantage 1: The numeral hieroglyphs can only represent 1 × 10^y numbers, such as 1, 10, 100, 1000 etc. It will be inconvenient for us to write out numbers like 899, 9999, where many numeral hieroglyphs are necessary. Disadvantage 2: The numeral hieroglyphs are hard to draw, such as that for 10^6. It will waste us lots of time in drawing those numeral hieroglyphs. The communication between mathematicians will be affected. How do you think? Please feel free to share your ideas!
