1. The problem is to perform calculations while rounding up to 2 decimal places at every step. 2. Rounding up means increasing the number to the nearest value with 2 decimal places, even if the digits after the second decimal are small. 3. For example, if a number is 3.141, rounding up to 2 decimals gives 3.15. 4. When performing calculations, after each operation (addition, subtraction, multiplication, division), round the result up to 2 decimals before proceeding. 5. This ensures that intermediate results do not lose precision due to rounding down. 6. Example: Calculate $1.234 + 2.345$ with rounding up at each step. 7. First, add: $1.234 + 2.345 = 3.579$. 8. Round up to 2 decimals: $3.579 \to 3.58$. 9. If next step is multiplying by 1.111, multiply: $3.58 \times 1.111 = 3.97838$. 10. Round up to 2 decimals: $3.97838 \to 3.98$. 11. This method keeps all intermediate results rounded up to 2 decimals. 12. Always apply rounding up after each calculation step to maintain consistency.
