How do I align my equations at the equals sign?
Math does not have a command for aligning equations on a particular character, but you can use a
matrix to do this, as shown below.

matrix{
alignr x+y # {}={} # alignl 2 ##
alignr x # {}={} # alignl 2-y
}
x+ y = 2
x = 2− y
The empty braces around = are necessary because = is a binary operator and thus needs an
expression on each side.
You can reduce the spacing around = if you change the inter-column spacing of the matrix:
1) With the equation editor open, choose Format > Spacing from the menu bar.
2) In the Spacing dialog (Figure 271), click the Category button and select Matrices in the
drop-down menu.
3) Enter 0% for Column spacing and click OK.

Changing the font size
This is one of the most common questions people ask about LibreOffice Math. The answer is
simple, but not intuitive:
1) Start the formula editor and choose Format > Font size.
2) Select a larger font size under Base size (top-most entry).
The result of this change is illustrated in Figure 273.
