Question

why 1 is called one and 2 is called 2
Happy Mathematics Day
bit please help me in this question​

Answer 1

Answer:

1 is called 1 bcoz numbers we write are made up of algorithms, (1, 2, 3, 4, etc) called Arabic algorithms

2 (without the bar at the bottom in the original, primitive text) would have only one angle where the diagonal line meets the vertical line.

3 written in primitive text is a "Z" with two angles, one where the top horizontal line meets with the diagonal line, and another where the bottom horizontal line meets with the diagonal line.

4 so if horizontal line meets angle form by the count of angle 1 is called 1 and 2 is 3
