LI: How to calculate the difference of whole numbers, using algorithms.
This week in Maths, I learned how to calculate the difference of whole numbers using the standard subtraction algorithm. I practiced lining up numbers by place value and subtracting carefully from right to left. When the top digit was smaller than the bottom digit, I used regrouping to borrow from the next column. This method helped me stay organized and avoid mistakes. I feel more confident subtracting larger numbers now, and I understand why following the steps carefully is important.
