How to write a vector in Latex

To write a vector in Latex, we can use
\vec function

$$\vec{AB} = 0_E$$

$$\vec{AB} = 0_E$$

or\overrightarrow function

$$\overrightarrow{AB} = 0_E$$

$$\overrightarrow{AB} = 0_E$$

Note: as Keyboard warrior said in the comments \overrightarrow function looks more like the vector symbol(s) we see in textbooks.
