Basic Operations on Literal Numbers
Since the literal numbers are used to represent numbers, they obey all the rules (including those of signs) regarding the operations of addition, subtraction, multiplication and division of numbers. For the same reason, literals satisfy all rules as well as properties of these operations.

Class 6 Maths Exercise 11.2 Important Questions
What are the four rules of algebra?
The Basic Laws of Algebra are the associative, commutative and distributive laws. They help explain the relationship between number operations and lend towards simplifying equations or solving them. The arrangement of addends does not affect the sum.
Write each of the following phrases using numbers, literals and the basic operation of addition: (i) The sum of x and 4 (ii) y added to 7 (iii) 6 more than a number x (iv) y added to the sum of x and 3.
(i) x + 4
(ii) y + 7
(iii) x + 6
(iv) (x + 3) + y
What do the letters mean in algebra?
In algebraic expressions, letters represent variables. These letters are actually numbers in disguise. In this expression, the variables are x and y. We call these letters “variables” because the numbers they represent can vary—that is, we can substitute one or more numbers for the letters in the expression.
What are literal numbers?
Literal numbers are the letters which are used to represent a number. The literal numbers are also known as literals. Literal numbers obey all the rules of addition, subtraction, multiplication and division of numbers. Thus, a + b means b is added to a.
What are the 4 basic operations?
The four operations are addition, subtraction, multiplication and division.
We can perform the required addition or subtraction, in numerical expressions. But in algebraic expressions which include letters, we can only indicate these operations, because we do not know the numbers these letters represent. For example, we can add 5 and 9, but we cannot add x and 3 because we do not know the number that x represents. In the latter case, we can only indicate the addition by writing x + 3. Likewise, we cannot subtract y from x, but we can indicate the subtraction by writing x – y.
