Question

What is the difference between: i) Variable and literal ii) Constant and Coefficient (in algebra (not programming))

Answer 1

$\bold{ \underline{\red{Variable \: and \: literal}}}$

literal is notation for representing a fixed ( const ) value. A variable is storage location associated with a symbolic name (pointed to, if you'd like). In any programming language a Literal is a constant value, where as identifiers can change their values

$\underline{ \bold{ \red{Constant \: and \: Coefficient}}}$

A coefficient is the number in front of the letter, eg =3x2

3 is the coefficient.

A constant is just a number

eg =y=3x2+7

7 is the constant.

Answer 2

Answer:

Variable and Literal

Variable, a name that can represent different value during the execution of the program.

Literal is not a name... it is the value itself.

Constant and Coefficient

A Coefficient is the number in front of the letter, eg- 3x 2 3 is the coefficient.

A Constant is just a number, eg- y=3x2+7

7 is the constant.
