(16 / (2(8 - 3(4 - 2)))) +1

= (16/(2(8 - 3(2)))) +1

= (16/(2(8-6)))+1

= (16/(2(2)))+1

= (16/4)+1

= 4+1

= 5

 

... and don't forget:

 

16 / (2(8 - 3(4 - 2)) +1)

= 16/(2(8 - 3(2)) +1)

= 16/(2(8-6)+1)

= 16/(2(2)+1)

= 16/(4+1)

= 16/5

 

... moral: when rendered in ascii, many equations are ambiguious without liberal use of parentheses.
