1) (7-6i)+(-5-2i)
\n" ); document.write( "= (7-2)+(-6-2)i
\n" ); document.write( "= 5-8i
\n" ); document.write( "-----------------------
\n" ); document.write( "2) (5-9i)-(-3-12i)
\n" ); document.write( "= (5--3)+(-9--12)
\n" ); document.write( "---
\n" ); document.write( "= 8+3i
\n" ); document.write( "=============
