- A constant is a number on its own.
For example, 1 or 127.
3. - A variable is a symbol, usually letters, which
represent a value or a number.
- A term is a constant or a variable or constants and
variables multiplied together. For example, 4, xy or
8yz. The term’s number part is called the numerical
coefficient while the variable or variables is/are
called the literal coefficeint/s. For the term 8yz, the
numerical coefficient is 8 and the literal coefficients
are yz.
