Graphical properties. Formula objects have similar properties in Calc, Impress, and Draw. They are always inserted with a transparent background and without borders. In Draw and Impress, they are assigned the Default graphical style; there is no assigned style for them in Calc and properties need to be specified explicitly. A formula can be positioned…

Numbering equations in Writer We can write numbered equations in Writer. Equation numbering is one of the Writer’s best hidden features. The steps are very simple. Start a new line in Writer. Type ‘fn’ and then press ‘F3’ from the keyboard. The ‘fn’ gets replaced by the numbered formula: E = mc2 (2) Now we…

Adjusting spacing. To increase or decrease the spacing between the different elements of a formula, click on ‘Format’ from the main menu bar and from the resulting menu, click on ‘Spacing’. This will open the ‘Spacing’ dialog box. In this dialog box, under ‘Spacing’, the spacing between different elements of an equation can be selected.…

Changing the font size. In LibreOffice Math, we can change the font size of the formulas. To change the font size of the formulas, click on ‘Format’ from the main menu bar and from the resulting menu, click on ‘Font Size’. This will open the ‘Font Sizes’ dialog box. In this dialog box, select the…

Adding limits to a sum or an integral. In Math, the ‘sum’ and ‘int’ commands are used for sum and limits respectively. These commands can take the parameters ‘from’ and ‘to’. These are used for lower and upper limits respectively. These parameters can be used singly or together. The usage of these commands and parameters…

In the basic installation, Math outputs variables in italics. If we enter a function, Math usually recognizes it and outputs it normally. If Math fails to recognize a function, we can inform Math about it by entering the markup code ‘func’ before the function. By using this code, the text following the code will be…

Using Brackets in Formulas The most difficult part in using LibreOffice Math is when writing complicated formulas. This is because LibreOffice Math knows nothing about the order of operations. We need to use brackets in order to state the order of operations explicitly. Consider the example which has been shown in the below given illustration.…

Greek characters (α, β, γ, θ, etc.) are common in mathematical formulas. These characters are not available in the Elements window or the right-click context menu in Math. Fortunately, the markup code for Greek characters is very simple. We just need to type a ‘%’ sign followed by the name of the character, in English.…

Another way of entering formulas into Math is by using the context menu. This menu can be accessed by right-clicking inside the editor window. The steps to be followed are almost similar to what were followed for using the elements window. To insert ‘7 x 8’, right-click inside the editor window and this will display…

The Elements Window is the simplest method of entering a formula in Math. The Elements window is divided into two main parts. The top part shows the symbol categories. These can be used to change the list of symbols. The bottom part shows the symbols available in the current category. So the different symbols can…
