From complex mathematical expressions to chemical formulae can be created in Word using the formula editor. The structuring options are a great strength.
Write a formula
We click on the Formulas button in the Symbols group in the Insert tab.
A menu with a selection of pre-configured formulas appears. Because we are creating a new formula in this example, we click on Insert new formula.
A formula box appears, which we click on.
Next we select the Draft tab. This is the formula editor with which we will create the formulas. This includes the Symbols group.
or the group structures.
Our first simple formula will be the Pythagorean theorem:
a² + b² = c²
Individual letters are entered in the formula field as usual. The superscript numbers are entered as follows:
We click on the high/low icon in the Structures group and select the superscript icon on the far left.
This is what our formula looks like now. Two placeholders for top and bottom.
We enter the letter a in the first field using the keyboard.
In the upper field we enter a 2.
We add characters (+,=) and other superscripts…
…. which we fill accordingly to get this result:
Insert mathematical special characters
The first example was a warm-up exercise. In this example we create the famous Fibonacci sequence:
As described in the last example, we insert a new formula and type F(n) = with the keyboard.
Since the Fibunacci series is a large fraction, we insert it as a foundation, so to speak. We click on the fraction symbol in the Structures group and select Fraction with horizontal hyphen on the far left.
This is how the formula looks now:
Next comes the phi sign with a superscript n. We click on the high/low symbol in the Structures group …
and select Superscript…
… to obtain this result:
Then we enter the Phi symbol that is not on the keyboard. In the Design tab, in the Symbols group, we click on the small black arrow, as in the example below.
The symbols menu opens and we click on the Phi symbol.
Our formula now has a Phi!
Next to the phi symbol we put the brackets with the keyboard. We type an n into the superscript placeholder. Add a minus and another superscript placeholder.
Now it gets a little complicated. The lower placeholder is a fraction. Therefore, we click on the lower placeholder and click on the fraction symbol in the Structures group and select the horizontal fraction (as in step 2).
In the placeholders we put the corresponding numbers and letters (and again the phi symbol).
The upper part of the fraction (numerator) is now finished – now we need the square root 5 in the denominator (lower part of the fraction). To do this, we select the root symbol in the Structures group and choose the square root option.
In the placeholder of the root we enter the number 5 and conclude the formula.
Arrange multiple formulas in a table
It is often necessary to present several formulas clearly. For this reason, we show a digression here.
For the tabular presentation we need a table. We click on the Insert tab and click on the table symbol and select a table with several rows (one row per formula) and two columns.
We click on the middle line of our table and hold down the left mouse button to change the column size.
The table is drawn so that the right-hand column is much smaller.
Now we insert the formula into our table in the left column. One formula for each row. The right column gets the numbering in brackets.
What bothers us is the table frame, which should be invisible. To remove it, we select the table and click on the small black arrow under the frame symbol on the Design tab in the Frame group.
A menu opens and no frame is selected.
Now format the table a bit and the result looks like this:
