audio read-through 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.)

 

Concept Practice

Write an expression to represent the sequence of operations.
