Solve the problems using sticks: addition (4+3), subtraction (8-5). Is it practical to solve large sums like 2358+4150 with sticks? Why is it difficult to solve large sums with objects?

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.

  $$4 + 3 = \boxed{7}$$

  The result is 7 sticks.

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

  $$8 - 5 = \boxed{3}$$

  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 quantity of objects to represent the numbers.
• 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 number of items.
