You can put this solution on YOUR website!
-12 is an integer since it is a number without any fractional/decimal parts to it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is also a rational number since -12 = -12/1. We can express -12 as a fraction of integers.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-12 is also a real number\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So far in your math course and previous courses, everything you've encountered is a real number. Any decimal number or fraction or square root of a positive number (etc etc) is a real number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You'll learn later on there are things called imaginary numbers or complex numbers which aren't real numbers\r

\n" ); document.write( "\n" ); document.write( "There are other types of numbers that go beyond the scope of your course, but you may learn about them later on in future math classes. \n" ); document.write( "
