Space:"\ " will give you a space in math expressions, notice the space after "\".

Vector and bar:  \bar a  gives you \(\bar a\),  \vec a  gives you \(\vec a\) and  gives you \(\overline{AB}\).

Under and above: \underset{a\ note\ here}{x+y+z}  gives you \(\underset{a\ note\ here}{x+y+z}\) and \overset{a\ note\ here}{x+y+z} gives you \(\overset{a\ note\ here}{x+y+z}\). To make it looks better we can us the code \underset{a\ note\ here}{\underbrace{x+y+z}} to get

\(\underset{a\ note\ here}{\underbrace{x+y+z.}}\)


Similarly  \overset{\text{ Some texts}}{\overbrace{(a+b+c+d)^2}}  gives you

\(\overset{\text{ Some texts}}{\overbrace{(a+b+c+d)^2.}}\)
