Making a bill — Money maths for kids

The method

Line by line — “work out each line of the bill, then add the lines”

1. Line cost = how many × price of one.
2. Total bill = add all the line costs.
3. Missing price = total − the lines you know.

Use it for: Checking a shop bill, school supply lists, and bill-making questions in Class 3–4 maths.

Worked example: Bill: 2 notebooks at ₹40 each, 1 geometry box at ₹120 and 3 pens at ₹15 each. What is the total bill (in ₹)? → 245
