All the following symbols and notations were introduced by Euler. So Great a man 🙌 🔥
Good morning ❤️

Two vectors are orthogonal if and only if their dot product is equal to zero.
If a square matrix A has a determinant of zero, the matrix is invertible
1 decillion (10³³) is the largest power of 10 known to humans that can be represented as the product of 2 numbers that contain no zero digits. A lot of mathematicians believe we won't find a larger number of this kind.

Leonhard Euler walked so every mathematician could run 😮💨🙇...

Fun fact: Romania’s president, Nicușor Dan, was one of the 11 students to solve the legendary Problem 6 at the 1988 IMO.
He scored a perfect 42/42 that year, alongside future Fields Medalist Ngô Bảo Châu. Ravi Vakil also solved it.
Terence Tao, aged just 13, got 1/7 on that problem, aced almost everything else, and still won gold.
Good morning ❤️
