A slash does not replace a horizontal line.

3+4

----- = 1

2+5

3+4/2+5=10

(3+4) / (2+5) = 1

This guy who just wrote in the problem with the inverse function left out the brackets. Maybe it is his teacher's fault. Getting the brackets correct is far more important than inverse functions.

Hi everybody,

I'd like to know once and for all which symbols to put

I have learned that                 : 

means division , now  the colon

means ratio.

so how to write division?

 

the slash        /            or

 the horizontal line ____

are used to indicate a fraction (a bar of fraction)

so how some write / slash as divison.

is

 / slash for both fraction an division?

Best wishes

Badriya
