Predict whether the instructions below will produce equivalent expressions. Then show whether your prediction is correct.

 • Subtract 3 from n, add 3 to the result, and then triple that expression. 

• Subtract 3 from n, triple the result, and then add 3 to that expression.

Due to the first instruction being tripled at the end of the expression, the results will not be equivalent.
