When somebody says 8+8*5 you know it is 48 by giving higher preceence to *. Supposing + was higher, it would have been 80. So, you need a convention to express what you want to. While it is very important to know the operator precedences correct. However, in higher mathematics, nobody encounters expressions like (6*7+3^4-8)/2. Everybody usually uses brackets and fractions to make it non-confusing.
