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:
It means thatis greater thanand '>'is the sign of 'greater than' or bigger than 'or more than'
is read as:
(a) is greater than
(b) is bigger than
(c) is more than
is also written asand read asis less than
Therefore, it is clear that the mouth of the sign '>' is open to the side of the greater or bigger number.
Howis a greater number betweenand 3?
For that we apply vertical line trick:
When countedis more than
Hence Take another example:
Which one is bigger betweenand?
Clearlyis more than
or
and or
It means the numberhas two digits and the numberhasdigit. Therefore,is greater than Take another example:

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 Three Numbers
Let's see the given below example:
Here, we have to subtract two numbersandbecause 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 concept of subtraction of three numbers clear.

Introduction
Subtraction means taking out something from some longer unit and in this process finding the outcome as left over. Let's understand this through an example: There are three eggs in the box given below:
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 subtraction and it is read as 'minus', and = is the sign of 'is equal to' or 'is same as'.
Thus,
It is read as
'three minus one is equal to two' or 'three minus one is same as two'.
Subtraction of two Numbers
It is the process of taking away smaller number from the greater one.
TRICK:
Here, it is clear that if we have to subtract then we cut three vertical lines from.It means number of vertical lines to be cut is equal for both greater and smaller numbers and number of vertical lines to be cut for each greater and smaller number is equal to the number to be subtracted.
Similarly, ifhas to be subtracted then number of vertical lines to be cut from greater number isand from smaller number is alsoAnd ifhas to be subtracted thenvertical lines are cut. Take another example:
Serena has 5 apples and she eats 3 apples. How many apples she has now?
(a) 1
(b) 4
(c) 3
(d) 2
Answer: (d)
Explanation
(a) 3

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.

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
Rupees
Then the numbers represent a figure. Therefore, it is clear that when numbers come in form of representing something, then they become a figure. Now, we add figures with simple method of addition we have learned so far.
Trick: =
Take another example
kg rice + kg pulse + kg sugar = ?
Trick:

(a) 11 rupees
(b) 10 rupees
(c) 12 rupees

Explanation
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.
(a) 8
(b) 6
(c) 12
(d) 9
Answer: (d)
Explanation
(a)
(b)
(c)
(d)
Answer:(a)
Explanation
In addition, if two or more numbers are added in any order the result is the same. In another words 1st number + 2nd number = 2nd number + 1st number
Therefore,
Further, we can check from the method:
Again,
Therefore,
Points to remember:
number +number =number +number
Option (B) is incorrect because =
Option (C) is incorrect because =
Option (D) is incorrect because
Concept of Addition
Addition means collection other than one unit together and counting them as single unit.
Let's understand this through an example:
There are three balls in box A
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 and it is read as 'plus' and '=' is the sign of 'is equal to' or 'is same as'
Thus,
is read as:
Three + One is equal to Four'
or 'Three + One is same as Four'
