From pyramids to various totems, the ancient Egyptians' talent in mathematics is shown. There is evidence that the ancient Egyptians began to invent numbers in 3000 BC, from the simplest 1 to 10, 100, 1000 and 10000. This time, let's see how they write numbers.

1. I don't know if you are talking about ancient Egyptian figures. I still use it now! If it is ancient:

First of all, do an exercise: if 1 is replaced by "-",draw an extra line for each additional one, then 2 is "=" and 4 is "= =". The mathematics of the ancient Egyptians was very similar to this. Initially, 1 to 9 were not represented by different numbers, but by the same symbol "repeatedly changing".

If we want to write a certain number, whether you are up or down, left to right, right to left, please remember: 1 When arranging numbers, put the same ones together; 2. The large number is at the front or upper end, that is, read the large number first.

2. Modernity is represented by the figures of * ancient India *:

- 0

-1 (oblique)? -1 (oblique)

- 2 ? - 2

- 3 ? - 3

-4 (like the left and right opposite 3)? -4 (like left and right opposite 3)

-5 (much like zero)? -5 (much like zero)

-6 (much like 7)? -6 (much like 7)

- 7 ? - 7

- 8 ? - 8

-9 (somewhat similar)? -9 (somewhat similar)

- 10 - 10
