You can put this solution on YOUR website!
For number 1, you add or subtract components. Your question is \"u-v\" and you have the components of u and of v.
\n" ); document.write( "u-v=( -3-(-8), -2-(-11) )
\n" ); document.write( "( -3+8, -2+11 )
\n" ); document.write( "( 5, 9 ). \n" ); document.write( "
