 The procedure for inserting an equation in your text is similar to 

 that for inserting a table.

 The macro to indicate the beginning of an equation is:

 .EQ

 The macro for ending an equation is .EN:

 .EN

 Since eqn output requires a typesetter, we'll walk you 

 through the process without showing the final product.

 To produce an x with a ^ on top, the command is:

 x hat                   # produces x with a hat

 To produce an x with a ~ on top, the command is:

 x tilde                 # produces x with a tilde

 To produce an italic x, the command is:

 x under                 # produces italic x

 To produce x divided by y, the command is:

 x over y                # produces x divided by y

 To have a square root sign drawn over ax**2 + bx + c, the command is:

 sqrt {ax sup 2 + bx + c}

 To redefine over from - to / command is:

 define / 'over'          # redefines over

 To produce the matrix:          x    z      the command is:

                                 y

                                 k    l

 matrix {

    ccol { x above y above k }

    ccol { z above nothing above l }

 }

 If the input file is called math, the command for preprocessing 

 the file with eqn and sending the output through troff is:

 Answer here:     

 That is correct!

 You've got it on the 2nd try.

 Good!  Now you understand the concept!

 Sorry, you must pipe the output of eqn to troff

 Sorry, the file name is the input for eqn

 Please review Preprocessors

FORGET6

 The correct answer is eqn math | troff

 NOTE, on your system, you may need to send the output of troff to 

 the col program which is used to take out reverse line feeds:

 eqn math | troff | col
