Guidance for solving problem 2 page 73 Mathematics 4 textbook (continued)
Solution method:
- Perform multiplication as usual, review how to place the multiplication operation in previous exercise solving instructions
- Check the calculation method in the given questions, then conclude whether the calculation is correct or incorrect.
Answer:
We have the second partial product consisting entirely of zeros (since 456 x 0 = 0), so we usually do not write this partial product and instead compact it as in method c (partial product 912 shifted two columns to the left compared to the first partial product).
Thus: Box 1 marked S ; Box 2 marked S ; Box 3 marked C.
