Why It Matters

Adding money is a basic skill for managing your finances and understanding daily transactions. It's crucial for budgeting, shopping, and even in careers like banking, accounting, and retail, where people constantly deal with money calculations.

Common Mistakes

MISTAKE: Not aligning the decimal point (or ones place for whole rupees) correctly when adding. | CORRECTION: Always align the decimal points or the ones place digits vertically before adding. This ensures you add rupees to rupees and paise to paise.

MISTAKE: Forgetting to carry over when the sum of digits in a column is 10 or more. | CORRECTION: When a column's sum is 10 or more, write the ones digit in that column and carry the tens digit to the next column on the left.

MISTAKE: Adding paise to rupees directly without converting or separating them. | CORRECTION: Remember that 1 Rupee = 100 Paise. Treat paise and rupees as separate units, adding paise to paise and rupees to rupees. If the paise total is 100 or more, convert 100 paise to 1 Rupee and carry it over.

₹215

₹225

₹125

₹200

The Correct Answer Is:

To find the sum, you add 150 + 75. 0 + 5 = 5 (ones place), 5 + 7 = 12 (tens place, write 2, carry 1), 1 (carried) + 1 = 2 (hundreds place). So the total is ₹225.
