How to | Suppress the Output of a Computation

Often you need to perform intermediate steps in a calculation but have no need to see the results. By suppressing the output you save memory to store the notebook and may even save formatting time. You will also be able to see the important parts of the notebook more easily.

You can suppress output in the Wolfram Language by placing a semicolon () at the end of the line:

For example, consider:

In[1]:=
Click for copyable input
Out[1]=

Suppress the output:

In[2]:=
Click for copyable input
    

This creates a small table of values and exports it to a text file. There is no point in seeing the numbers, so the result is suppressed:

In[1]:=
Click for copyable input
Out[1]=
    

You can also use to condense multiple lines into a single line. The output here is 2 since only the output of the last statement, , is displayed:

In[1]:=
Click for copyable input
Out[1]=

Use at the end to stop any output:

In[2]:=
Click for copyable input

Using to chain commands extends to any number:

In[3]:=
Click for copyable input
Out[3]=
