Writing formulas in Word

Maths and physics books contain complicated expressions such as fractions, powers and roots, which are hard to type as plain text. Word has an equation editor for this: the Equation button in the Symbols group of the Insert tab (in older versions labelled “Формула”) or the Alt+= shortcut. A field for the formula appears where the cursor was and the Equation tab opens. It has two parts: Symbols – relation signs (≤, ≥, ≠), Greek letters and operators; Structures – fraction, superscript and subscript, radical, integral, brackets and functions. When you choose a structure, boxes appear inside it for you to fill with numbers, moving between them with Tab or the arrow keys. To leave the editor, click once on an empty part of the page. If a formula has a mistake, click it, put the cursor in the right place and correct it. Modern Word also has quick linear input: type 1/2 and press Space and it becomes a fraction; type x^2 and press Space and you get a power.
