IT'S EXACTLY LIKE MATHS, YES! YOU HAVE TO KNOW WHICH SIGNS YOU HAVE TO 'SOLVE' FIRST (like x comes before +) BUT THEN YOU HAVE TO PAY ATTENTION BECAUSE THEY CAN TOTALLY TRICK YOU (like, a + in a parenthesis comes before a x outside of it.)

I DUNNO IF THIS MADE ANY SENSE BUT THIS IS HOW I FELT DURING THAT CLASS OMG I FAILED MATHS WHY DO I HAVE TO DO THIS AGAIN AAAAH *brb rocking back and forth in fetal position nao*
