## What is a Product Sum Calculator?

A Product Sum Calculator is a simple tool or program that takes two numbers as input and performs two operations on them: multiplication and addition. It calculates the product (multiplication) of the two numbers and also calculates their sum (addition).

The main purpose of a Product Sum Calculator is to provide the user with the result of both operations in a convenient way. The user can enter any two numbers, and the calculator will show them the product and sum of those numbers.

For example, if the user enters the numbers 4 and 5, the Product Sum Calculator will calculate:

- Product: 4 * 5 = 20
- Sum: 4 + 5 = 9

So, the calculator will display that the product of 4 and 5 is 20, and the sum of 4 and 5 is 9.

It’s a straightforward tool that can be useful in various scenarios, such as basic arithmetic calculations, educational purposes, or any situation where you need to quickly find the product and sum of two numbers.

## The formula of product sum

The formula of the product sum refers to a quadratic equation that involves finding two numbers whose product and sum are given. Let’s assume the two numbers as “x” and “y,” and we are given the product as “product” and the sum as “sum.”

The formula of the product sum is as follows:

- Product Equation: x * y = product
- Sum Equation: x + y = sum

To find the specific values of “x” and “y,” we can follow the steps:

- Rearrange the Sum Equation to express one of the variables in terms of the other variable: y = sum – x
- Substitute this value of “y” in the Product Equation: x * (sum – x) = product
- Simplify the equation: x^2 – sum * x + product = 0
- Use the quadratic formula to solve for “x”: x = [sum ± √(sum^2 – 4 * product)] / 2
- Once you find the value of “x,” you can find the corresponding value of “y” using the Sum Equation: y = sum – x

The quadratic equation may have two real solutions, one real solution, or two complex solutions, depending on the discriminant (sum^2 – 4 * product). If the discriminant is negative, it means there are no real solutions.

## How to find Numbers for the given product and sum?

You can use algebraic equations to find two numbers given their product and sum. Let’s assume the two numbers as “x” and “y” and the given product and sum as “product” and “sum,” respectively.

The problem can be formulated as a system of equations as follows:

- Product Equation: x * y = product
- Sum Equation: x + y = sum

### Here’s a step-by-step method to find the numbers “x” and “y”:

- Given the product and sum values, write down the two equations as shown above.
- Rearrange the Sum Equation to express one of the variables in terms of the other variable: y = sum – x
- Substitute this value of “y” in the Product Equation: x * (sum – x) = product.
- Simplify the equation and put it in the standard quadratic form: x^2 – sum * x + product = 0
- Use the quadratic formula to solve for “x”: x = [sum ± √(sum^2 – 4 * product)] / 2
- Once you find the value of “x,” you can find the corresponding value of “y” using the Sum Equation: y = sum – x

Keep in mind that the quadratic equation may have two real solutions, one real solution, or two complex solutions, depending on the discriminant (sum^2 – 4 * product). If the discriminant is negative, it means there are no real solutions.

#### Example:

Let’s say we want to find two numbers whose product is 20 and the sum is 9.

Given: product = 20, sum = 9

- Product Equation: x * y = 20
- Sum Equation: x + y = 9
- Substituting “y = 9 – x” in the Product Equation: x * (9 – x) = 20
- Simplifying the equation: x^2 – 9x + 20 = 0
- Using the quadratic formula to solve for “x”: x = [9 ± √(9^2 – 4 * 20)] / 2 x = [9 ± √(81 – 80)] / 2 x = [9 ± √1] / 2Therefore, the two values of “x” are: x1 = (9 + 1) / 2 = 5 x2 = (9 – 1) / 2 = 4
- Find the corresponding values of “y”: For x1 = 5, y = 9 – 5 = 4 For x2 = 4, y = 9 – 4 = 5

So, the two numbers whose product is 20 and the sum is 9 are 4 and 5.

## What is the product sum and difference formula?

The product, sum, and difference formulas are mathematical identities that express the result of specific operations involving two variables or numbers. These formulas are often used in algebra and trigonometry to simplify expressions, solve equations, or derive new equations.

- Product Formula: The product formula expresses the result of multiplying two binomials. It is commonly known as the “FOIL” method, which stands for “First, Outer, Inner, Last.”Given two binomials (a + b) and (c + d), their product is calculated as follows: (a + b)(c + d) = ac + ad + bc + bdThis formula is used to expand expressions like (x + 3)(x – 2) or (2a + 5)(3a – 1).
- Sum Formula: The sum formula expresses the result of adding two terms or numbers. For example, given two numbers “a” and “b,” their sum is simply: a + bThis is a basic arithmetic operation used to find the total when combining two or more quantities.
- Difference Formula: The difference formula expresses the result of subtracting one term or number from another. For example, given two numbers, “a” and “b,” their difference is: a – b. This is another basic arithmetic operation to find the gap or distance between two values.

## What sum is 27 and the product is 182?

To find two numbers whose sum is 27 and whose product is 182, we can use the method described earlier. Let’s assume the two numbers as “x” and “y,” and we are given the sum as 27 and the product as 182.

- Product Equation: x * y = 182
- Sum Equation: x + y = 27

To find the specific values of “x” and “y,” we can follow the steps:

- Rearrange the Sum Equation to express one of the variables in terms of the other variable: y = 27 – x
- Substitute this value of “y” in the Product Equation: x * (27 – x) = 182
- Simplify the equation and put it in the standard quadratic form: x^2 – 27x + 182 = 0
- Use the quadratic formula to solve for “x”: x = [27 ± √(27^2 – 4 * 182)] / 2 x = [27 ± √(729 – 728)] / 2 x = [27 ± √1] / 2Therefore, the two values of “x” are: x1 = (27 + 1) / 2 = 14 x2 = (27 – 1) / 2 = 13
- Find the corresponding values of “y”: For x1 = 14, y = 27 – 14 = 13 For x2 = 13, y = 27 – 13 = 14

So, the two numbers whose sum is 27 and product is 182 are 13 and 14.

For finding two numbers whose sum is 15 and product is 36, we can use the method described earlier. Let’s assume the two numbers as “x” and “y,” and we are given the sum as 15 and the product as 36.

- Product Equation: x * y = 36
- Sum Equation: x + y = 15

To find the specific values of “x” and “y,” we can follow the steps:

- Rearrange the Sum Equation to express one of the variables in terms of the other variable: y = 15 – x
- Substitute this value of “y” in the Product Equation: x * (15 – x) = 36
- Simplify the equation and put it in standard quadratic form: x^2 – 15x + 36 = 0
- Use the quadratic formula to solve for “x”: x = [15 ± √(15^2 – 4 * 36)] / 2 x = [15 ± √(225 – 144)] / 2 x = [15 ± √81] / 2Therefore, the two values of “x” are: x1 = (15 + 9) / 2 = 12 x2 = (15 – 9) / 2 = 3
- Find the corresponding values of “y”: For x1 = 12, y = 15 – 12 = 3 For x2 = 3, y = 15 – 3 = 12

So, the two numbers whose sum is 15 and product is 36 are 3 and 12.

## What are two integers whose product is 45 and whose sum is 18?

To find two integers whose product is 45 and sum is 18, we can follow the method described earlier. Let’s assume the two integers as “x” and “y,” and we are given the product as 45 and the sum as 18.

- Product Equation: x * y = 45
- Sum Equation: x + y = 18

To find the specific values of “x” and “y,” we can follow the steps:

- Rearrange the Sum Equation to express one of the variables in terms of the other variable: y = 18 – x
- Substitute this value of “y” in the Product Equation: x * (18 – x) = 45
- Simplify the equation and put it in standard quadratic form: x^2 – 18x + 45 = 0
- Use the quadratic formula to solve for “x”: x = [18 ± √(18^2 – 4 * 45)] / 2 x = [18 ± √(324 – 180)] / 2 x = [18 ± √144] / 2Therefore, the two values of “x” are: x1 = (18 + 12) / 2 = 15 x2 = (18 – 12) / 2 = 3
- Find the corresponding values of “y”: For x1 = 15, y = 18 – 15 = 3 For x2 = 3, y = 18 – 3 = 15

So, the two integers whose product is 45 and sum is 18 are 3 and 15.

Given: sum = 10, product = 24

- Sum Equation: x + y = 10
- Product Equation: x * y = 24
- Substituting “y = 10 – x” in the Product Equation: x * (10 – x) = 24
- Simplifying the equation: x^2 – 10x + 24 = 0
- Using the quadratic formula to solve for “x”: x = [10 ± √(10^2 – 4 * 24)] / 2 x = [10 ± √(100 – 96)] / 2 x = [10 ± √4] / 2Therefore, the two values of “x” are: x1 = (10 + 2) / 2 = 6 x2 = (10 – 2) / 2 = 4
- Find the corresponding values of “y”: For x1 = 6, y = 10 – 6 = 4 For x2 = 4, y = 10 – 4 = 6

So, the two numbers whose sum is 10 and product is 24 are 4 and 6.
