# The Division Command

The **Division** command is used to do manipulations on the **Div** object. The
keystroke for the **Division** command is "*d*".

The **Division** command can be used in two different ways if you highlight an expression
that has the form "a/b", the **Division** command will typically return several different
options that split out some of the terms that were originally in the highlighted
expression.

If you highlight a single term in either the numerator or denominator of a division
expression, the **Division** command will extract that term from the division expression.
For example, in the expression

x*y/z

with the "x" highlighted, the **Division** command will return x * (y/z)

The **Division** command can also act on added terms, for example, on the expression

a/b + c/d

the **Division** command will return

(a*d + c*b)/b*d

In these kinds of expressions, the **Division** command will also search for the least
common multiple and build the expression that has that in the denominator. So for

a/4 + c/14

the **Division** command generates

(7a + 2c)/28

In some cases, the **Division** command will return multiple results. When this happens,
the result list popup window is displayed to allow you to select among the returned
results.
