that's the way I do it, Hacker's way is to write [tex]\not =[/tex] if that helps you to remember

Here are a few more LaTeX codes you may enjoy ... or not.

**\circlearrowleft**. $\displaystyle \circlearrowleft$ . . .**\circlearrowright**. $\displaystyle \qquad\circlearrowright$

**\curvearrowleft**. $\displaystyle \curvearrowleft$ . .**\curvearrowright**. $\displaystyle \curvearrowright$

**\rightsquigarrow**. $\displaystyle \rightsquigarrow$

**\bar{x}**. $\displaystyle \bar{x}$

**\langle**. $\displaystyle \langle$ . . . .**\rangle**. $\displaystyle \rangle$

**\hdots**. $\displaystyle \hdots$ . .**\cdots**. . $\displaystyle \cdots$ . .**\ddots**. $\displaystyle \ddots$

**\pmod{n}**. $\displaystyle \pmod{n}$

**\boxed{x = 1}**. $\displaystyle \boxed{x = 1}$

**9\choose3**. $\displaystyle 9\choose3$ . . .**\binom{9}{3}**. $\displaystyle \binom{9}{3}$

**\!**. removes a space

. .**\sin^2x + \cos^2x**produces: $\displaystyle \sin^2x + \cos^2x$

. . . . . . . . . . . . . . . . . . . . . . . . . .$\displaystyle \uparrow$ . . . . $\displaystyle \uparrow$

I found that the extra spaces can be confusing.

They can be removed with:**\sin^2\!x + \cos\!x**: .$\displaystyle \sin^2\!x + \cos^2\!x$

Thanks! That can be useful. :) Can someone show me how to make a Pascals triangle with LaTex code? Creating a new row with

Ok thanks, doing it with code tags seems simple.

How do you make a degree-sign? Like a $\displaystyle \circ$ but higher up...
