11.6 Subscripts, Bars and Other Modifiers

Here is a typical palette of modifiers.

Mathematica TE allows you to use any expression as a subscript.

In[1]:=

Out[1]=

Unless you specifically tell it otherwise, Mathematica TE will interpret a superscript as a power.

In[2]:=

Out[2]=

Special input forms based on control characters. The second forms given should work on any keyboard.

This enters a subscript using control keys.

In[3]:= Expand[(1 + x _1+n )^4]

Out[3]=

Just as ^ and _ go to superscript and subscript positions, so also & and = can be used to go to positions directly above and below. With the layout of a standard English-language keyboard & is directly to the right of ^ while = is directly to the right of _.

Ways to enter some common modifiers using control keys.

Here is .

In[4]:= x &_

Out[4]=

You can use as a variable.

In[5]:= Solve[a^2 == %, a]

Out[5]=

Ways to enter modifiers without control keys. All these forms can be used only inside \!\( ... \).
