Summary: Problem Set 9 – Addition Word Problems

A word problem tells a short story with numbers. First find out what is asked.

Words such as 'altogether', 'in all', 'total', 'together' and 'sum' tell us to add.

Write the numbers in a column with the places lined up, then add from the units, carrying when needed.

Always write the answer as a full sentence with the right unit — rupees, metres, votes, children.

Some problems hide the numbers, like 'the smallest six-digit number' — first write that number (1,00,000), then add.

Key points to remember

• Read the problem twice
• Find what is asked
• 'Altogether', 'total', 'in all' → add
• Write the numbers in columns
• Add from the units and carry
• Answer in a sentence with the unit
• Smallest six-digit = 1,00,000; largest = 9,99,999
• Estimate to check the answer

Problem Set 9 – Addition Word Problems – Notes

1. Four steps for any word problem

• 1. Read: what is the story about, and what is the question?
• 2. Choose: which operation? For 'how many altogether', choose addition.
• 3. Solve: write the numbers in columns and add.
• 4. Answer: write a sentence, e.g. 'Altogether 4,34,224 trees were planted.'

2. A solved problem

• Keep the units of the story in the answer — rupees stay rupees, trees stay trees.
• Line up the digits carefully even when the numbers are long.

3. Hidden numbers

• Smallest five-digit number = 10,000; largest = 99,999.
• Smallest six-digit number = 1,00,000; largest = 9,99,999.
• Smallest seven-digit number = 10,00,000; largest = 99,99,999.
• Write these down first, then do the sum.

4. Money problems

• If someone buys two things, the total cost is the sum of the two prices.
• A bike for ₹68,450 and a helmet for ₹2,375 cost ₹68,450 + ₹2,375 = ₹70,825.
• Write ₹ in the answer.

5. Is my answer sensible?

• The total must be bigger than each of the numbers you added.
• Round and add quickly: 2,46,815 ≈ 2.5 lakh and 1,87,409 ≈ 2 lakh, so about 4.5 lakh. 4,34,224 is close — good!
