 
LibreOffice
has a formula module sometimes referred
to as the math module
this feature can be used in Libre
office writer
to create formatted mathematical and
scientific formulas
when we do this
the formula is placed in a frame
to insert a formula we go up to insert
object
formula
this opens up a box at the bottom of the
screen
and opens up an element dialog box
if the element dialog box does not open
you can't turn it on
by going into view
elements
there it is
if I click on the different
icons in the top half of the elements
dialog box
will notice that the items on the lower
part of the dialog box change
i want to add in a simple fraction
one-half plus two thirds
starting in this far left corner looking
down below I see one that may be a
good fit
for what they want to do
a over b
clicking that
at the bottom of the screen we see this
less than a question mark greater than
over
and then in curly braces we see the same
thing and the other side
up on our sheet we see of box over a box
this is asking us
what do you wanna put in the top for a
fraction
i want this want to be one
over two
now that i know what the formatting
is like
i'll do the same thing
plus
two over three
there i have my one-half
plus two thirds
clicking outside of my frame or my lower
box
takes me back
to the standard libre office writer
settings
if i want to edit this formula
i would just double click it
and it brings back
my elements dialog box
and my formula box down below
let's change this formula to one-plus
X over two
I'm clicking inside the curly braces
and I see one plus
x
over too
if i do the same thing to our other side
2 plus X
we see that it made the two by itself and
we have plus two plus x over three which
is not what we wanted
i can put this in parentheses
and that gives me my two-plus X
over three
so we see the difference between the
curly braces in the parentheses they do
the same thing
only the curly braces are not seen
in our formula
clicking in the document
outside of my formula takes me back to
the the libreoffice writer document
let's add another formula
insert
object
formula
we want to put in square roots symbol
we need to look along the top
clicking our icons until we see it now
i see it right here
that shows us how to put it down there
square root and it gives us the box that
we've seen before
taking out the less than a question mark
greater than box
will make it the square root of
three X
now that we know how to put a square
root symbol in there let's add it to our
first formula
i'm going to make this first one
sqrt
adding a curly brace to the left
and a curly brace to the right
now we've got the square root of
one-plus x over two
