Out of 1,80,000 Vitamin A tablets, 18,734 distributed. Find remaining.
Remaining = 1,61,266
Goal: Subtract the distributed tablets from the total.
Step 1: Write the numbers.
Total tablets:
\[ 1,80,000 \]
Distributed tablets:
\[ 18,734 \]
So we need:
\[ \text{Remaining} = 1,80,000 - 18,734 \]
Step 2: Regroup to handle zeros.
There are many zeros in 1,80,000. We borrow from the left to make subtraction easy.
\[ 1,80,000 = 1,70,000 + 10,000 \]
\[ 10,000 = 9,000 + 1,000 \]
\[ 1,000 = 900 + 100 \]
\[ 100 = 90 + 10 \]
After regrouping, the digits act like:
\[ 1\;\text{lakh},\;7\;\text{ten-thousands},\;9\;\text{thousands},\;9\;\text{hundreds},\;9\;\text{tens},\;10\;\text{ones} \]
Step 3: Subtract place by place (right to left).
Ones:
\[ 10 - 4 = 6 \]
Tens:
\[ 9 - 3 = 6 \]
Hundreds:
\[ 9 - 7 = 2 \]
Thousands:
\[ 9 - 8 = 1 \]
Ten-thousands:
\[ 7 - 1 = 6 \]
Lakhs:
\[ 1 - 0 = 1 \]
Step 4: Write the answer.
\[ 1,80,000 - 18,734 = 1,61,266 \]
Remaining tablets = 1,61,266.
