document.write( "For the penny, you have 2 opportunities: it either is included to the sum, or not.\r\n" );
document.write( "\r\n" );

document.write( "For the dime, you have the same 2 opportunities: it either is included to the sum, or not.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For the quarters, you have 4 opportunities: Either 0, or 1, or 2, or 3 quarters are included.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For loonie (Canadian one-dollar coin), you have 2 opportunity, again.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now, multiply the numbers of these opportunities. You will get\r\n" );
document.write( "\r\n" );
document.write( "    2*2*4*2 = 32.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this total number 32, we should subtract the zero sum case.\r\n" );

document.write( "\r\n" );
document.write( "So, the final answer is  32-1 = 31 different non-zero sums.\r\n" );
