Going From an Expression to a Sequence of Operations
Need some practice going the other direction? Going from a Sequence of Operations to an Expression
The expression $\,2x + 1\,$ represents the sequence of operations ‘take a number, multiply by $\,2\,,$ then add $\,1\,$’.
The expression $\,2(x+1)\,$ represents the sequence of operations ‘take a number, add $\,1\,,$ then multiply by $\,2\,$’.
(Of course, a variable other than $\,x\,$ can be used.)
