As with any type of language, math has actually a way to interact concepts. An algebraic expression is a compact way of describing mathematical objects using a combination of numbers, variables (letters), and also arithmetic operationsnamely enhancement, subtractivity, multiplication, and also division.

You are watching: N divided by 8 in algebraic expression

In other words, the 3 main components of algebraic expressions are numbers, variables, and also arithmetic operations.

Numbers or Constants

Examples:1, 6, 8, 27, 32, and so on.

Variables or Letters

Examples:x, y, a, h, p, etc.

Arithmetic Operations

Examples:+ (addition), - (subtraction) , imes (multiplication) , ÷ (division)

The adhering to are basic examples that can aid you obtain familiarized with the operations of addition, subtraction, multiplication,and department.

the sum of x and also 5 → x+5

Subtraction

the distinction of y and also 3 → y-3

Multiplication

the product of n and also 2 → 2n

Division

the quotient of k and 7 → Largek over 7

## Writing Algebraic Expressions Step-by-Step Examples

Let’s go over even more examples.

Example 1: The sum of twice a number and also 3

Answer: Let variable x be the unwell-known number. So twice a number implies 2x. The sum (usage plus symbol) of twice a number and 3 have the right to be composed as 2x+3.

Example 2: The distinction of triple a number and also 5

Answer:Let variable y be the unrecognized number. So triple a number suggests 3y. The difference (use minus symbol) of triple a number and 5 have to be written as 3y - 5.

Example 3:The sum of the quotient of m and also 2, and also the product of 4 and also n.

Answer:In this case, the unrecognized numbers are already provided as m and n. That’s one much less point to problem.

The crucial is to recognize that we are going to add a quotient and a product.

the quotient of m and also 2 is expressed as Largem over 2the product of 4 and also n is expressed as 4n

Thus, the sum of the quotient and product is Largem over 2 + 4n.

Example 4: The distinction of the productof 7 and also w, and also the quotient of 2 and v.

Answer: In this case, the unknown numbers have been assigned with equivalent variables which are w and v.

The vital is to recognize that we are going to subtract the product by the quotient of some expressions.

the product of 7 and also w is expressed as 7wthe quotient of 2 and also v is expressed as Large2 over v

Therefore, the distinction of the product and also quotient is 7w - Large2 over v.

## Common Words or Terms to Typical Addition, Subtractivity, Multiplication, and also Division

Now, let’s go over some prevalent words or phrases that explain the four arithmetic operations. It is crucial that you knowthese words or phrases to be effective in creating or interpreting any type of provided algebraic expression.    ## Math Phrases right into Algebraic Expressions

The key to finding out is to research a LOT of examples!
