Question

Find the sum and product of 7,11 and 91 .

Short answer

Answer: The sum of the numbers 7, 11, and 91 is 109, and their product is 7007.

Step-by-step solution

Finding the Sum of the Numbers

To find the sum of the numbers, we need to add all the given numbers: 7, 11, and 91. So, the sum will be: Sum = 7 + 11 + 91

Calculate the Sum

Now, we will add the numbers: Sum = 7 + 11 + 91 = 18 + 91 = 109 So, the sum of the given numbers is 109.

Finding the Product of the Numbers

To find the product of the numbers, we need to multiply all the given numbers: 7, 11, and 91. So, the product will be: Product = 7 * 11 * 91

Calculate the Product

Now, we will multiply the numbers: Product = 7 * 11 * 91 = 77 * 91 = 7007 So, the product of the given numbers is 7007. In conclusion, the sum of the numbers 7, 11, and 91 is 109, and their product is 7007.

Key concepts

Understanding Addition

Addition is one of the fundamental arithmetic operations. It involves calculating the total of two or more numbers by combining them into a single sum. In the exercise, we are tasked with finding the sum of 7, 11, and 91.
To do this, we begin by adding the first two numbers:

• 7 + 11 = 18.

This result gives us an intermediary sum of 18
Next, we add this intermediary sum to the third number:

• 18 + 91 = 109.

That's how we arrive at a total sum of 109. Addition is straightforward and involves moving left to right, combining numbers in a step-by-step manner.
By consistently practicing addition, it becomes easier to perform these operations mentally and quickly, an important skill for everyday calculations.

Exploring Multiplication

Multiplication is another core arithmetic operation, often seen as repeated addition. It combines groups of numbers to find a total number. In the exercise, the product of numbers 7, 11, and 91 needs to be found.
The process begins by multiplying the first two numbers:

• 7 \( \times \) 11 = 77.

After finding this product, we move on to the next step, multiplying this result by the third number:

• 77 \( \times \) 91 = 7007.

Thus, the total product is 7007. Multiplication simplifies the process of adding the same number multiple times and makes handling larger numbers much more efficient.
Multiplication is critical in many areas of mathematics and helps to understand patterns and relationships between numbers.

Basics of Arithmetic

Arithmetic underpins basic mathematics and involves operations like addition and multiplication. When dealing with arithmetic, it is important to understand how these operations connect.

• Addition combines numbers to increase their total.
• Multiplication builds on addition, allowing for quick calculations by grouping numbers.

Basic arithmetic is everywhere, from managing finances to cooking recipes. Mastering these operations allows individuals to tackle more complex math topics.
Honing skills in basic arithmetic is essential, as it lays the groundwork for algebra, calculus, and beyond. Consistent practice in these operations leads to numerical fluency and confidence in handling daily numerical challenges.
