Multiplication of two Numbers
Only
numbers are involved in this types of problems, the following are the correct steps that are used in it.
Step I:
Write down the numbers to be multiplied in columns as shown below:
Where, T = Tens and 0 = Ones
Step II:
Multiply ones as below:
Write down under ones column as below:
Step III:
Multiply tens as shown below:
Write 2 under tens column.
Now, add 2 tens and 4 ones = 24
Introduction
Multiplication is a repeated addition. Let's understand this through an example: How many eggs are there in the two boxes given below?
Here,
Number of boxes
Number of eggs in each box
Total number of eggs in the two boxes: 
eggs.
But in short, we can write as :
[x' is the sign of multiplication]
Now, we can say that
two's is equal to
ormultiplied by
is equal to.
In other words, we say that the product of andis more...
Word Problems
In this section, we will learn about some real life examples based on subtraction.
There are

Subtraction of Figures
When a number represents something particular, then it becomes a figure.
For example:
hours, 
apples.
minutes,
rupees etc.
hours -
hours = hours
Solution:
Subtraction of Images
Similarly,
Now it is clear how images are subtracted.
Subtraction of Five Numbers
To subtract the five numbers, the subtraction pattern remains same as discussed in the previous topic.
Solution:
1st We add the numbers with '-' (minus) sign and write the result.
Now subtract
from
. 
Take another example:
Solution:
add
and
(Numbers with minus sign) and write the result.
Subtraction of Four Numbers
Let's understand it through the examples given below:
Solution:
First add
and
as
Now subtract
Here, first add
and
and write the result with - sign.
Now add
and
and write the result with + sign. more...
Subtraction of Three Numbers
Remember the steps for the subtraction:
Step I: Add the numbers having '-' (minus) sign and write the result with - sign.
Step II: Add the numbers having '+' (plus) sign and write the result with + sign. This method is applied when addition and subtraction are given simultaneously.
Step lll: Finally subtract the numbers.
Note: This method goes same for any subtraction. No matter, how many numbers are involved in the given subtraction problem. In another words this method is applied for the subtraction of
numbers;
numbers; 
numbers; 
numbers and so on.
Solution:
Step I:

Subtraction of two Numbers
Let's understand it by the examples given below:
Solution:
Here, we cannot subtract
from
(or ones from
ones) so we borrow (orten) leaving behind
(ortens) and then the format becomes as below:
Thus the process goes for any subtraction where ones of the greater number is less than ones of the smaller number.
Solution: more...
Addition of Figures
When a number represents something it becomes a figure. Addition of figures is done in the same way as the addition of numbers for example,
pencils,
coins,
ice creams etc. are called figures.
pencils +
pencils = 
pencils
Solution:
pencils +pencils
homes +
homes + 
homes
homes.
Solution:
more...
Addition of Five Numbers
For the addition of five numbers follow the rules given below:
Step I: Add the 1st three numbers.
Step II: Add the remaining two numbers.
Step III: Add step I and step II.
To get this result follow the method:
Step I:
Step II:
Step III:
Step I + Step II,
Again to get this result we follow the same three steps.
