I am trying to do multi step math and keep returning the wrong answer
显示 更早的评论
I am given the equation and this is my code but it keeps telling me that it is returning the wrong value.
b=(1/7)+((72/13)^2)/(sqrt((125/2)-(25/3)))

How is the value wrong?
How precise do you want the output value to be?

The expression and the code match, so you are good.
How is the test case in Grader comparing the value with the output?

Of course it is wrong. Why did you write 72/13? Why 25/3?
I think you don't understand that
8(1/3) is NOT the same thing as
8 + 1/3
Similarly, you see essentially
5 (7/13)
and you are trying to add fractions!
b=(1/7)+((5*7/13)^2)/(sqrt((125/2)-8*1/3))
Do you see what you are doing? When you have an expression like that, you should not assume an implicit addition there. I think you are confused because some people will write
5 1/2
as meaning 5 PLUS 1/2, and thus effectively 5.5.

Exactly. It took me a few seconds to recognize what you had done. And now that I think of it, I can see the subtle ambiguity. One of those optical illusions in a sense, that you can look at a picture in several different ways.

Also be careful when you guys use WolframAlpha.
Case 1: Without space
Case 2: With space

Even I took them as mixed fractions and responded accordingly. I was going to ask for a clarification but in the mean time John had already answered the question.
