\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3 - (-4)
\n" ); document.write( "= 3 + 4 {minus a negative becomes plus}
\n" ); document.write( "= 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5 - (-3)
\n" ); document.write( "= 5 + 3 {minus a negative becomes plus}
\n" ); document.write( "= 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-3 - 4
\n" ); document.write( "= -7 {just add 3 and 4 and put a negative in front}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3 - 4
\n" ); document.write( "= -1 {imagine standing on 3, on the number line, and moving 4 to the left}
