strange... given you sample files and the script:
Code:
#!/bin/ksh

paste maya1.txt maya2.txt |\
 awk '{for(i=1;i<=NF/2;i++) printf("%s%s", $i+$((NF/2)+i), (i==NF/2)?ORS:OFS)}'

I get the desired result:
Code:
72 74 76 78 80
92 94 96 98
112 114 116
132 134
152

Can you run cat -vet on both files and post the corresponding output within code tags, please.

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

DIAGNOSTICS

     The column utility exits 0 on success, and >0 if an error occurs.

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; 
	   printf "HH:MM/YEAR NAME
" ; 
	   ls -l | sed 1d) | column -t

SEE ALSO

HISTORY

     The column command appeared in 4.3BSD-Reno.
