What are some common mistakes in operator precedence?

What are some common mistakes people make with operator precedence?

One common mistake is assuming that all operators have the same precedence. For example, many people forget that multiplication and division have higher precedence than addition and subtraction.

Can you give me an example of that?

Sure! In the expression 3 + 4 * 5, many might think it evaluates to 35, but it actually evaluates to 23 because multiplication is performed before addition.

What about parentheses? How do they affect precedence?

Parentheses can change the order of operations. In the previous example, if you write (3 + 4) * 5, it evaluates to 35 because the addition inside the parentheses is done first.

Are there any other common mistakes?

Yes, another mistake is neglecting to consider operator associativity, which determines the order of operations for operators of the same precedence.
