Explanation :
Multiplication Expression in Algebra includes
Multiplication Operator
Literal Numbers
and Constants
For example = 5x, ab, 22pqr
In the above example we have :
Literal Numbers = x, a, b, p, q & r.
constants = 5 & 22.
In Multiplication Expression in Algebra, remember the following points :
1). Omission of multiplication sign between a number and a literal number.
For example = (5 × y) is written as (5y) and (27 × a) is written as (27a)
2). Omission of multiplication sign between two or more literal numbers.
For Example = (x × y) is written as (xy), (a × b) is written as (ab) and (p × q × r) is written as (pqr)
3). When there is a product of a number and a literal number, number is always placed on the left side of the literal number.
For Example = (5 × x) or (x × 5) both are written as 5x.
