1.10.6 Subscripts, Bars and Other Modifiers

  • Here is a typical palette of modifiers.
  • Mathematica allows you to use any expression as a subscript.
  • In[1]:=

    Out[1]=

  • Unless you specifically tell it otherwise, Mathematica 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 \!\( ... \ ).
