# Going From a Sequence of Operations to an Expression

Need some practice going the other direction? Going from an Expression to a Sequence of Operations

The sequence of operations
‘*
take a number,
multiply by
* $\,2\,$, *then add* $\,1\,$’
is represented by
the expression
$\,2x + 1\,$.

The sequence of operations
‘*
take a number,
add
* $\,1\,$,
*then multiply by* $\,2\,$’
is represented by
the expression
$\,2(x+1)\,$.

(Of course, a variable other than $\,x\,$ can be used.)
