jtur88 is right, the problem is written in poor fashion. It is intentionally written to be vague and cause confusion. Nobody with a strong background in math would have ever written the expression that way. That is what parentheses, brackets and braces are used for...to provide clarity on how the problem was intended to be interpreted.
It wasn't vague, confusing, or ambiguous for Excel, Matlab, and Google.
Exactly.
Depending on how you set the calculator.
Both ways are correct. It can be interpreted in either of the ways you showed up there.
No because the order of operation are set...
You can change the rule of algebra just because you dont like it...
I posted a link of the order of
After this I hope this subject would be finish..
Source: Order of Operations
Quote:
Rule 1: First perform any calculations inside parentheses. Rule 2: Next perform all multiplications and divisions, working from left to right. Rule 3: Lastly, perform all additions and subtractions, working from left to right
U can search any source you want online or your text books, they all say is left to right... Unless you can find me a link that say otherwise I dont see the point to continue with this subject.
Apparently, this is a semantic difference in the way the symbols were used when they were first introduced and the way ÷ is commonly used today. I thought this was an interesting find:
No, you have to change your calculator as a scientific, i search the subject and if you use a regular calculator the calculator goes step by step that you enter it, you must change the calculator to scientific mode...
The problem is not necessarily with the calculator but the entry mode that you used.
Different calculators follow different orders of operations. Most non-scientific calculators without a stack work left to right without any priority given to different operators, for example giving while more sophisticated calculators will use a more standard priority, for example giving
Here are the difference:
On a formula calculator one types in an expression and then presses 'Enter' to evaluate the expression.[1][2][3] There are various systems for typing in an expression: infix, postfix, natural display etc.
On an immediate execution calculator, the user presses a key for each operation, by pressing keys to calculate all the intermediate results, before the final value is shown.
You must put formula, if not the calculator just follow your input and not the rule of algebra.
Again, I have paste the rules of algebra,, have you read them??
If after reading them and you still dont understand the left to right rule, then I dont understand why continue on the subject..
Again just do a search of order of operations and that is it...
I wont continue on this subject, is like fighting over if the sky is blue after i have shown you that it is blue but you continue saying is red...
Apparently, this is a semantic difference in the way the symbols were used when they were first introduced and the way ÷ is commonly used today. I thought this was an interesting find:
You solve the denominator first then divide the numerator by it
