GIVE AND TAKE 
CLASS 3
Addition & Subtraction are our "give and take" math heroes! 
They help us in daily life:
Counting plants in a garden 
Managing money 
Finding out how much more is needed 
Let’s explore how numbers help us solve problems every
day!

SUBTRACTION IN
ACTION
Subtraction helps us find out how much is left after giving away or
using something.
Example: A farmer, Kishan, had 456 saplings. 
He gave away 63 saplings to villagers.
To find out how many were left:
456 - 63 = 393 saplings.
Subtraction helps in real life, like sharing, managing stock, and
planning!

Kishan got an order of 230 saplings from a school. He
packed 75 saplings. How many Saplings more do he need
to pack ?

CONCEPT OF ADDITION AND
SUBTRACTION USING BOX DIAGRAM
In the box diagram, we'll break down the numbers into Hundreds
(H), Tens (T), and Ones (O).
Total saplings ordered: 230
Saplings already packed: 75

Total saplings ordered: 230
Saplings already packed: 75
STEP 1: DRAW A BOX DIAGRAM
Ones Column:
0 - 5 is not possible, so borrow 1 ten from the Tens column.
3 tens become 2 tens, and now we have 10 ones.
10 - 5 = 5 ones.
Tens Column:
After borrowing, we have 2 tens.
2 tens - 7 tens is not possible, so borrow 1 hundred from the
Hundreds column.
2 hundreds become 1 hundred, and now we have 12 tens.
12 - 7 = 5 tens.
Hundreds Column:
1 hundred remains (since there’s nothing to subtract from it).
