Just like any type of language, math has a way to connect ideas. One algebraic expression is a compact method of relenten mathematical objects utilizing a combination that numbers, variables (letters), and also arithmetic operationsnamely addition, subtraction, multiplication, and division.

You are watching: Twice the sum of a number and 3 algebraic expression

In various other words, the three main components of algebraic expressions are numbers, variables, and 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) , imes (multiplication) , ÷ (division)

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


the amount of x and 5 → x+5


the difference of y and 3 → y-3


the product that n and also 2 → 2n


the quotient that k and 7 → Largek over 7

Writing Algebraic expressions Step-by-Step instances

Let’s walk over an ext examples.

Example 1: The sum of twice a number and 3

Answer: Let change x be the unknown number. So twice a number way 2x. The sum (use to add symbol) of twice a number and 3 deserve to be composed as 2x+3.

Example 2: The distinction of triple a number and 5

Answer:Let change y be the unknown number. Therefore triple a number means 3y. The difference (use minus symbol) that triple a number and also 5 have to be written as 3y - 5.

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

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

The vital is to identify that we are going come add a quotient and also a product.

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

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

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

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

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

Common native or terms to typical Addition, Subtraction, Multiplication, and Division

Now, let’s go over some typical words or unit volume that define the four arithmetic operations. That is an essential that friend knowthese indigenous or phrases come be effective in writing or interpreting any kind of given algebraic expression.
