Multiplication


Let Us Learn About Multiplication

Multiplication means times (or repeated addition). The symbol used for multiplication is '×'.

For example : 4 (Multiplicand) × 8 (Multiplier) = 32 (Product)

example for multiplication 4 × 6 = 24.

To learn Multiplication we should learn multiplication tables first.

This is read as four times six is equal to twenty-four or simply, four times six is twenty-four.

Multiplications indicates by placing the quantities to be multiplied side by side (just a position). The important of multiplications process is to place the digits value of the factors in the proper columns. That is, units number must be placed in the units column, tens in tens column, and hundreds in hundreds column. Notice that it is not essential to write the zero in the case of 15 tens (150) since the 1 and 5 are written in the proper columns.


In our next blog we shall learn about properties of Multiplication.


Addition


Let Us Learn About Addition


Without Math life is impossible.

Math is the one skill you need to master in your life, even if it is the only one, you will at least be able to live without being cheated, robbed or abused. You see, without math we just cannot live or survive. We need math in our everyday lives. Just doing the basic essentials is dependent on your ability to do math.

Now let us understand what is addition.

Addition is a basic operation in mathematics; addition has simple rules. Addition role in math problems are important in most of the problems. Addition is an arithmetic operation it can be done in many math formulas and in upper grade problems addition is continued. Addition is denoted by logic operator plus “+” When plus present between the numbers we have to add in this section we have problems with addition for two, three digit numbers.


The arithmetic is considered as the branch of math which deals with the operations of counting the numbers. The study of arithmetic involves the study about the volume of the object. There are four basic arithmetic operations are present to add, subtract, multiply and divide the numbers. Here in this article we are going to see about these basic arithmetic operations.

Basic Arithmetic Operations

Basic operations:

The basic arithmetic operations are given as,

  • Addition
  • Subtraction
  • Multiplication
  • Division


To learn addition you should learn numbers


Let Us learn with some examples



Try to solve the below problems.

add 3 and 9 add 2 and 3 add 6 and 6

3 2 6
+9 +3 +6
____ _____ _____
____ _____ _____

Factors and multiple


Let Us Learn About Factors and multiple


What is Multiple?


When two numbers are multiplied together, the result is called a multiple

6 is a multiple of 2 and 3

9 is a multiple of 3 only

10 is a multiple of 5 and...

Can you say what the other number is?

A multiple of a number is a number obtained by multiplying it by a natural number.


If we multiply 3 by 1, 2, 3, 4, 5, 6… ,we get 3×1 = 3, 3×2 = 6, 3×3 = 9, 3×4 = 12, 3×5 = 15, 3×6 = 18 … Thus, 3, 6, 9, 12, 15, 18 …are multiples of 3 Clearly, a number is a multiple of each of its factors. The multiples of 4 are 4, 8, 12, 16, 20, 24, 28… Each of these multiples is greater than or equal to 4.

What is Factors?
The numbers that make a multiple are called factors

2 and 3 are factors of 6

3 is also a factor of 9

10 has two factors

Can you say what they are?

A factor of a number is an exact divisor of that number. In other words, a factor of a number is that number which completely divides the number without leaving a remainder. Each of the numbers 1, 2, 3, 4, 6 and 12 is a factor of 12. However, none of the numbers 5, 7, 8, 9,10 and 11 is a factor of 12.



let us understand with example, 8 divides 40 exactly, therefore 8 is a factor of 40.Similarly, 4 is a factor of 16 and 5 is a factor of 25.


Note: "1" is the common factor of every number and every number is always a factor of itself.

1 is the only number which has exactly one factor, so it is a unique number.
