Solve the following addition and subtraction problems using sticks as visual aids. Also, discuss the practicality of using sticks for large numbers.

Here are the solutions to the problems:

1. Solve the problems using the sticks given below:

• Addition: The first group has 4 sticks. The second group has 3 sticks.

  $$4 + 3 = 7$$

  The result is 7 sticks.

• Subtraction: The first group has 8 sticks. The second group has 5 sticks.

  $$8 - 5 = 3$$

  The result is 3 sticks.

2. Is it possible to solve sums with large numbers such as $2358 + 4150$ using these sticks?

• No, it is not practical to solve sums with such large numbers using individual sticks.

3. Why is it difficult to solve large sums using objects?

It is difficult to solve large sums using objects because:

• You would need an extremely large number of objects to represent the numbers, making it impractical to gather and store them.
• Counting and manipulating thousands of individual objects would be very time-consuming and prone to errors.
• It would be hard to keep track of such a large quantity of items, especially during complex operations.
