Introduction

Multiplication is one of the four fundamental operations in arithmetic. It is usually denoted by the cross (×), or on computers by an asterisk (*). Addition, subtraction, and division make up the remaining three operations. The result of a multiplication operation is a product.

The multiplicand, multiplier, and product are all components of a multiplication problem.

Multiplying two numbers is similar to making as many copies of the multiplicand as there are multipliers. One way to think of multiplying whole numbers is as repeated addition. You can consider both numbers to be factors of the product.

However, we divide them into columns for multiplication of higher digits numbers according to their respective place values, such as ones, tens, hundreds, thousands, and so on. One-digit numbers can be multiplied simply by using multiplication tables to solve multiplication problems. There are two multiplication problems:

Detailed Explanation

The number 123 can be multiplied by any other number to get the 123 times table. Also, this table can be achieved by adding the “122” number multiple times in ascending order. The table of 123 is depicted in the chart below.

The first ten multiples of 123 are listed here to make math for pupils pleasant and fascinating.

123	×	1	=	123	123
123	×	2	=	244	123 + 123 = 244
123	×	3	=	369	123 + 123 + 123 = 369
123	×	4	=	492	123 + 123 + 123 + 123= 492
123	×	5	=	615	123 + 123 + 123 + 123 + 123 = 615
123	×	6	=	738	123 + 123 + 123 + 123 + 123 + 123 = 738
123	×	7	=	861	123 + 123 + 123 + 123 + 123 + 123 + 123 = 861
123	×	8	=	984	123 + 123 + 123 + 123 + 123 + 123 + 123 + 123 = 984
123	×	9	=	1107	123+123 + 123 + 123 + 123 + 123 + 123 + 123 + 123= 1107
123	×	10	=	1230	123 + 123 + 123 + 123 + 123 + 123 + 123 + 123 + 123 + 123 = 1230

As you can see, multiplication of numbers by 123 follows a straightforward procedure. However, a number of approaches can be used to streamline and improve this process.

The commutative property is one of the strategies for multiplication that is most frequently applied. This feature ensures that the product is unaffected by the order of the number multiplication. For instance, the outcomes of 123 x 2 and 2 x 123, 246, are the same. This characteristic can be advantageous when multiplying higher digits numbers.

Hints And Shortcuts

The following is a list of tips and shortcuts for multiplying numbers.

When multiplying, it doesn't matter where the integers are placed. Choose the sequence that seems more logical to you. When using multiplication tables, students might find it simpler to recall 4×8 than 8×4.
For instance, if we try to multiply 5×18 initially, it will be challenging and if we try to multiply 5×18×2 then it will be less challenging. Because, multiplying 5 and 2 together yields 10, which may be multiplied by 18 to get 180..
When multiplying a two-digit integer by a one-digit number occasionally helps to separate the two-digit integer into its place values. Then multiply each component before combining. For instance, you may figure out 37× 4 mentally by splitting 37 into 30 + 7. As a result, 7×4 = 28 and 30×4 = 120. The final answer is 148 since 120 plus 28 equals 148. Conceptually, this is much easier to solve than it might first appear to be when written down.
You can still calculate the multiplication fact mentally even if you can't remember it. For instance, it's challenging to remember 18×9. This can, however, be mentally organised as 18×(10 - 1). As a result, the answer is 180 – 18 = 162.

Advantages Of Using Times Tables For Mathematical Calculations:

The ability to quickly and easily perform calculations for large quantities or measurements.
Simplification of comparisons between quantities or measurements.
Capability to solve complex mathematical equations and problems.

One of the key benefits of using tables is the ability to quickly and easily perform calculations for large quantities or measurements. For example, when determining the total square footage of a space, a table can be used to quickly calculate the area by multiplying the length and width. This can save time and effort compared to manually performing the calculation.

Another advantage of tables is their ability to simplify comparisons between quantities or measurements. For instance, when comparing the capacity of two containers, a table can be used to quickly determine which container can hold more liquid by multiplying the volume of each container by the liquid's density.

Tables also have the capability to solve complex mathematical equations and problems, such as calculating the area of a triangle or determining the volume of a cylinder. This can make it easier to understand and solve these types of problems, even for those who may struggle with more advanced mathematical concepts.

When it comes to multiplication, tables can be used in different ways like regrouping, without regrouping, using a number line etc. These methods can help simplify and speed up the multiplication process. By understanding and utilizing these strategies, individuals can improve their multiplication abilities and overall math confidence and success.

Frequently Asked Questions (FAQs)

1. What is the value 123 × 9 ?

The value of 123 × 9 is 1107.

2. Does 123 × 5 and 5 × 123 give the same value?

Yes,123 × 5 and 5 × 123 give the same value, i.e. 615.

3. What is the method of multiplication by number line?

The method of multiplication by number line is a visual representation of the multiplication operation. It involves using a number line, which is a straight line of numbers, to demonstrate the concept of repeated addition. To perform multiplication on a number line, one starts at the number 0 and repeatedly moves to the right side of the number line, adding the corresponding number of units for each iteration. This method can be especially useful for teaching the concept of multiplication to young students or for those who struggle with traditional methods of multiplication.

4. What is the square root of 123?
