# Mathjax bug?

### Steps to reproduce

${x,y}$

{x,y}

### Actual result

the opening bracket { is not rendered, the letter x becomes boldface

### Environment

• Operating system: OSX
• Debug info:

@Chau This is not a bug. LaTeX uses curly braces for grouping. To produce curly braces in the output, you need to precede them with a backslash:

$\{x,y\}$


I did put the backslash in but it is not rendered on this forum. Could you try it on your end? I apologize for this newbie question. Chau

This forum doesn’t support LaTeX math.
