Introduction
Comparison enables us to identity what is greater or smaller between two objects and what is greatest and smallest among more than two objects.
For example, if we compare
&
, it is clear thatis bigger number but if we compare
&
then
is the smallest andis the biggest number.
Whilecomes between&therefore, it is greater or bigger than but smaller or less than.
Comparison of Numbers
Let us see the given below examples:
Subtraction of Images
It means taking out picture or pictures from group of pictures and finding the remaining as the result of the subtraction.
Take another example:
Here, we count the flowers given before the sign of minus and after the sign of minus. We subtract it through the normal method of subtraction.

Subtraction of Figures
Numbers 
etc
Figures = 2 rupees, 3 books, 1 kg, 6 hours, etc.
Now, how to subtract figures?
In fact, we subtract figures with simple method of subtraction we have learned so far.
hours -
hours =
hours
Trick:
Take another example:
Trick:
bananas -bananas -
banana 8 Bananas -(2 Bananas + 1 Bananas)

Subtraction of Three Numbers
Let's see the given below example:
Here, we have to subtract two numbers
and
because both numbers have '_' sign.
Now,
Step 1: Add the numbers with '_' sign.
Step 2: Do subtraction as subtraction of two numbers.
Thus,
Take another example:
Here,
Step 1: Add numbers with ' + ' sign
Step 2: Do the subtraction as subtraction of two numbers.
Thus,
Therefore, above given two examples makes the more...
From this box Steve eats one egg then how many eggs are left?
Steve eats one egg then one egg will disappear from the box as shown below:
Now two eggs are seen in the box. Therefore, this means two eggs are left over and the outcome of this subtraction process is 2.
Let's understand it another way:
Total eggs in the box = 3
= egg eaten by Steve
And 2 = outcome or left over
Here, '_' is the sign of more...
Addition in Column
Addition in column is done by adding the numbers in column. See the given below
Addition of Images
It does mean grouping of two or more pictures together.
pictures +
picture =
pictures.
Here,
we count all the umbrellas together and find that they are 8 in total.
umbrellas +
umbrellas =
umbrellas.
Add the balloons given below and choose the correct option. 
(a) 
(b)
Addition of Figures
Figure
Let's consider about 2, 4, 11, 10, etc. In fact these are simply numbers.
But, when we say:
Mangoes
Kilogram
Letters
hours
Trick: =
Take another example
kg rice + 
kg pulse + 
Addition of Two Numbers
It is the grouping of two numbers together and counting them as a single number. 
It is also written as:
Trick: Put two vertical lines for 2 and three vertical lines for 3. After this count all the lines together and that line will be the final result of this addition. 
or
Now,
Take another example
Now,
we follow the trick:
Add the numbers inside the egg given below.

There is one ball in another box B
Now,
How many balls are there in both the boxes together?
For this, we put the balls from both the boxes in a single box as shown below:
Therefore, the third box has three balls of box A and one ball of box B and they are together 4 balls.
Let's understand it in another way:
or
Where '+' is sign of addition
