sum = (-2i)(1 + 6i) - (5i)(-1 + 2i)
\n" ); document.write( "a - b
\n" ); document.write( "a = (-2i)(1 + 6i)
\n" ); document.write( "b = (5i)(-1 + 2i)
\n" ); document.write( "---
\n" ); document.write( "recall: ii = -1
\n" ); document.write( "---
\n" ); document.write( "a = (-2i)(1 + 6i)
\n" ); document.write( "a = -2i + (-2i)(6i)
\n" ); document.write( "a = -2i + (-12ii)
\n" ); document.write( "a = (-2i + 12)
