Inputting fraction and math operations

Posted 10 years ago

I'm using this website the first time and I'm struggling to write this input. I checked also the examples but they didn't help. I've problems with -9 and + 2 1/5. How to write it so the engine will understand it?

Not quite. It should be:

(3/2)/(-9/14) + 2 + 1/5

Use round brackets, ( ), to indicate precedence. Spaces between two numbers are taken as Times, so 2 1/5 becomes (2*1)/5. In fact, in an Input cell it should show a gray "x" symbol standing for Times.

The last "Plus" is too much

In[83]:= (3/2)/(-9/14) + 2 (1/5)
Out[83]= -(29/15)

Is it right like this? 3/2-9/14+ 2 1/5?
