Just like any type of language, math has a method to interact ideas. One algebraic expression is a compact method of explicate mathematical objects using a combination the numbers, variables (letters), and arithmetic operationsnamely addition, subtraction, multiplication, and also division.
You are watching: 9 less than the quotient of n and 5
In various other words, the 3 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) , \\times (multiplication) , ÷ (division)
The complying with are easy examples that can aid you acquire familiarized through the operations of addition, subtraction, multiplication,and division.Addition
the amount of x and 5 → x+5Subtraction
the difference of y and also 3 → y-3Multiplication
the product of n and also 2 → 2nDivision
the quotient the k and also 7 → \\Largek \\over 7
Writing Algebraic expressions Step-by-Step examples
Let’s go over more examples.
Example 1: The sum of double a number and 3
Answer: Let change x be the unknown number. So twice a number method 2x. The amount (use add to symbol) of double a number and 3 have the right to be composed as 2x+3.
Example 2: The difference of triple a number and 5
Answer:Let variable y be the unknown number. For this reason triple a number method 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 provided as m and also n. That’s one less thing to worry.
The vital is to recognize that we are going come add a quotient and a product.the quotient of m and 2 is expressed as \\Largem \\over 2the product that 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 the quotient the 2 and v.
Answer: In this case, the unknown numbers have actually been assigned with matching variables which are w and v.
The an essential is to acknowledge that we are going to subtract the product by the quotient of part 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.
