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

You are watching: 3 less than the product of 5 and a number

In various other words, the three main components of algebraic expressions room 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 instances that can help you obtain familiarized through the operations of addition, subtraction, multiplication,and division.

Addition

the sum of x and also 5 → x+5

Subtraction

the difference of y and 3 → y-3

Multiplication

the product of n and 2 → 2n

Division

the quotient the k and 7 → Largek over 7

Writing Algebraic expressions Step-by-Step examples

Let’s go over an ext examples.

Example 1: The amount of double a number and 3

Answer: Let change x be the unknown number. So twice a number means 2x. The amount (use to add symbol) of double a number and also 3 deserve to be written as 2x+3.

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

Answer:Let variable y be the unknown number. So triple a number method 3y. The difference (use minus symbol) the triple a number and 5 need to be created as 3y - 5.

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

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

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

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

Therefore, the amount of the quotient and also product is Largem over 2 + 4n.

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

Answer: In this case, the unknown numbers have been assigned with corresponding variables which space w and also v.

The crucial is to identify that we are going come subtract the product through the quotient of some expressions.

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

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