What are the types of expression?

Answers

Answer 1

There is major 3 types of expression. Numerical expression, algebraic expression and fractional expression.

What is numerical expression?

This expression contains only two or more numbers along with symbols or operator. There is no variable present.

such as 226÷113+2×22-11

or (44÷88) ×100%

the above sign is percentage sign we can determine a percent value

or∛ (64)

the above sign represents a cubic root

we get the value 4

What is fractional expression?

The expression having two or more fractional terms along with symbols are called fractional expression. There are numerator and denominator from which we need to determine a common denominator to obtain a result.

such as, 4/5+3/4

we have 2 different denominators 5 and 4. we need to find a common denominator by multiplying both. 5x4

In the next, common denominator is divided by each denominator and the result is multiplied with each numerator.

(4×4+3×5)/20

hence, the result is 31/20

What is algebraic expression?

The expression contains both variables and numbers along with symbols are called algebraic expression. The algebraic expression having equal sign are termed as equation. Tha main purpose of using equation is to determine unknown value.

Algebraic expression are different types such as linear expression

2x+3-4y

2 and 4 are coefficient, 3 is constant

Polynomial expression as example 2x²-3y+4

Besides, we have other algebraic expression such as 3y+4 or x/4+y/3

and so on.
