Just like any type of language, math has actually a way to interact ideas. An algebraic expression is a compact means of describing mathematical objects using a combination the numbers, variables (letters), and arithmetic operationsnamely addition, subtraction, multiplication, and also division.

You are watching: The quotient of c and 6

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

Numbers or Constants

Examples:1, 6, 8, 27, 32, etc.

Variables or Letters

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

Arithmetic Operations

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

The complying with are easy examples that can aid you get familiarized with the to work of addition, subtraction, multiplication,and division.

the amount of x and 5 → x+5

Subtraction

the difference of y and 3 → y-3

Multiplication

the product of n and also 2 → 2n

Division

the quotient that k and 7 → \Largek \over 7

## Writing Algebraic expressions Step-by-Step examples

Let’s walk over more examples.

Example 1: The sum of twice a number and 3

Answer: Let variable x it is in the unknown number. So twice a number method 2x. The amount (use to add symbol) of double a number and 3 can be created as 2x+3.

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

Answer:Let change y it is in the unknown number. So triple a number way 3y. The difference (use minus symbol) that triple a number and also 5 should be written as 3y - 5.

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

Answer:In this case, the unknown numbers room already listed as m and also n. That’s one much less thing to worry.

The key is to acknowledge that we are going to add a quotient and also a product.

the quotient the m and 2 is expressed together \Largem \over 2the product that 4 and also n is expressed together 4n

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

Example 4: The difference 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 corresponding variables which are w and also v.

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

the product the 7 and w is expressed together 7wthe quotient that 2 and also v is expressed together \Large2 \over v

Therefore, the difference of the product and quotient is 7w - \Large2 \over v.

Now, let’s go over some usual words or paragraph that describe the 4 arithmetic operations. It is vital that you knowthese indigenous or phrases to be successful in writing or interpreting any type of given algebraic expression.    ## Math Phrases into Algebraic Expressions

The vital to discovering is to examine a the majority of examples!
