Understanding basic arithmetic, particularly addition, is crucial for solving this mass calculation problem. Adding numbers, especially with decimals, requires careful alignment and attention.
- Begin by stacking the numbers vertically ensuring the decimal points are aligned. This alignment is important to maintain place values.
- Add each column starting from the rightmost side, progressing towards the left.
- Carry over any excess to the next column when a sum exceeds ten, just like in single-digit addition.
In the exercise, the sum was performed as follows:
- Add 1.07 kg, 6.0 kg, and 6.05 kg carefully to get the correct total of 13.12 kg.
- Each part of the operation is crucial; missing just one decimal can change the outcome.
Accurate arithmetic is fundamental in physics and daily life - mastering it with small numbers builds confidence for more complex calculations.
