Table of 87

Introduction:

In general, multiplication is a mathematical operation that involves multiplying two or more numbers to find their product. The result of a multiplication operation is called a product. To multiply two numbers, we simply need to add the first number to itself the number of times indicated by the second number. For example, to multiply 3 by 4, we would add 3 to itself 4 times: 3 + 3 + 3 + 3 = 12.

To multiply 87 by another number, we would use the same process. For example, to multiply 87 by 2, we would add 87 to itself once: 87 + 87 = 174. To multiply 87 by 3, we would add 87 to itself three times: 87 + 87 + 87 = 261. And so on for other numbers.

It's important to note that multiplication is commutative, which means that the order in which we multiply numbers doesn't matter. In other words, 87 x 2 is the same as 2 x 87, and the result will be the same in both cases.

Below is the table of 87 using both, the multiplication and addition processes. While we directly multiply the numbers with 87, we add 87 repeatedly with itself the number of times till we get the desired result.

Exploring the Patterns and Rules of table 87:

One interesting pattern to note when multiplying 87 by other numbers is that the digits of the product always add up to 15. For example, when we multiply 87 by 2, the product is 174, and the digits 174 (1 + 7 + 4) add up to 12. When we multiply 87 by 3, the product is 261, and the digits 261 (2 + 6 + 1) add up to 9. And so on for other numbers. This is a general rule that holds for all numbers that are multiples of 87.

Another interesting pattern to note is that the units digit of the product is always 7 when we multiply 87 by an odd number. For example, when we multiply 87 by 3, the product is 261, and the units digit of 261 is 1. When we multiply 87 by 5, the product is 435, and the units digit of 435 is 5. And so on for other odd numbers.

Usage and Importance of multiplication table of 87:

Multiplication is a fundamental mathematical operation that is used in many different fields and applications. Some examples of real-world applications of multiplication include:

• In everyday life, multiplication is used in a variety of situations, such as calculating the cost of a group of items, figuring out how much paint is needed to cover a wall, or determining the total distance travelled by a vehicle travelling at a certain speed for a certain amount of time.

• In science and engineering, multiplication is used in many different ways, such as calculating the force of an object based on its mass and acceleration, determining the volume of a container based on its length, width, and height, or calculating the density of a substance based on its mass and volume.

• In finance and economics, multiplication is used to calculate the total value of a portfolio of investments, the return on investment for a given investment, or the total amount of money that a person will have after a certain number of years if they invest a certain amount at a certain interest rate.

• In statistics, multiplication is used to calculate the probability of certain events occurring, such as the probability of rolling a certain number on a pair of dice, or the probability of drawing a certain card from a deck of cards.

These are just a few examples of how multiplication is used in the real world. It is a fundamental mathematical operation that is essential for many different fields and applications.

Solved examples & real-world applications:

The multiplication of 87 can have many practical applications in the real world, depending on the context in which it is used. Here are a few examples:

• In the kitchen, if a recipe calls for 87 grams of a certain ingredient, you can use multiplication to calculate how much of that ingredient you need if you want to make a larger or smaller batch of the recipe. For example, if you want to double the recipe, you would need 2 x 87 = 174 grams of the ingredient.

• In retail, if a store sells a product for Rs 87/- and you want to know the total cost of buying a certain number of those products, you can use multiplication to calculate the cost. For example, if you want to buy 3 of the products, the total cost would be 3 x Rs 87/- = Rs 261/-

• In finance, if you want to calculate the future value of an investment that earns a certain rate of interest compounded annually, you can use multiplication to determine how much the investment will be worth after a certain number of years. For example, if you invest Rs 87 at an annual interest rate of 3%, after 10 years the investment will be worth 87 x (1 + 0.03)^10 = Rs 122.12.

These are just a few examples of the practical applications of multiplication of 87. In general, multiplication is a fundamental mathematical operation that is used in many different fields and contexts to perform calculations and solve problems.
