-5 + (-2) = -5 - 2 = -7
\n" ); document.write( "---
\n" ); document.write( "put a mark at -5, five units in the negative direction (to the left of zero)
\n" ); document.write( "---
\n" ); document.write( "-2 means subtract 2 from the above mark (from the -5 mark), so move two units in the negative direction (to the left of the -5 mark), and put a new mark
\n" ); document.write( "---
\n" ); document.write( "the new mark is at -7 on the number line.
