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+5Subtraction
the difference of y and 3 → y-3Multiplication
the product of n and 2 → 2nDivision
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.
