For test case 9 it reads:

“The expression 5 - 9 + 5 should produce a result of 1

AssertionError: The expression 5 - 9 + 5 should produce a result of 1”

In my mind, this is immediate execution. If it were formal logic, then the equation would evaluate the `9+5`

then evaluate `5-14`

which would yield `-9`

. Am I misunderstanding this? Shouldn’t the addition operator take precedence over the subtraction operator?
