This question was marked as an exact duplicate of an existing question.

$5-0*3+9/3 =5-(0*3)+(9/3)$ as '*' has precedence over '-' and '+', '/' has precedence over '+'. $=>5-0*3+9/3 =5-0+3$ – lab bhattacharjee Aug 19 '12 at 16:22
Why don't you either learn how to type with latex in this site (pretty easy) or at least tray to separate the expressions to udnerstand what is it? Is it $\,5-0\times3+\frac{9}{3}\,$ , or perhaps $\,5-\frac{0\times 3+9}{3}\,$ , or $\,5-0\times\frac{3+9}{3}\,$ , or something else? – DonAntonio Aug 19 '12 at 16:24
@labbhattacharjee : To me it seems uncouth to write $0*3$ instead of $0\times3$ or $0\cdot3$. The only reason anyone ever used $*$ for that purpose is that when one is restricted to the characters on the keyboard and one wants to use x as the name of a variable in computer programs, one must use something else for $\times$. But we have $\TeX$ and we don't need to do that. It's like eating mashed potatoes with your fingers when silverware is available. – Michael Hardy Aug 19 '12 at 16:26
@DonAntonio It is my first question . I will learn latex. – Serious Aug 19 '12 at 16:29
@Serious, since this is your first question on math.SE, please don't take this question closure as a hostility against you (or new users), and don't get discouraged to post further questions. It's just that this site works better if we re-cycle and re-use existing questions and answers, and then tag/label duplicate questions & link them together. – user2468 Aug 19 '12 at 16:54

$$5-0\times 3+9/3=5-0+9/3=5-0+3=5+3=8$$

Assuming, of course, the above is what you meant to write.

Shouldn't we add 0 and 3 before subtracting. ? – Serious Aug 19 '12 at 16:28
@Serious see this colorful answer by robjohn♦. – user2468 Aug 19 '12 at 16:37

The original expression becomes 5-0+3, which is 8. By the way, this shouldn't have the tag (linear-algebra). Put it in arithmetic.

Fixed the tag . – Serious Aug 19 '12 at 16:26
The second part really ought to be a comment, not in an answer, and the first part isn't very well explained. – Ben Millwood Aug 19 '12 at 19:31
