Understanding the Problem

Anna has 5 notebooks, but she needs 11. To determine how many more notebooks she needs to buy, we can use basic arithmetic operations.

Breaking Down the Problem

Let's break down the problem into smaller parts:

  • Anna has 5 notebooks.
  • Anna needs 11 notebooks.

Using Basic Arithmetic Operations

To find out how many more notebooks Anna needs to buy, we can subtract the number of notebooks she has from the number of notebooks she needs.

Subtraction Operation

Subtraction is a basic arithmetic operation that involves finding the difference between two numbers. In this case, we need to subtract 5 (the number of notebooks Anna has) from 11 (the number of notebooks Anna needs).

Calculating the Difference

Let's perform the subtraction operation:

11 (number of notebooks Anna needs) - 5 (number of notebooks Anna has) = ?

To calculate the difference, we can count down from 11 by subtracting 5:

11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

By counting down, we can see that the difference between 11 and 5 is 6.

Conclusion

Therefore, Anna needs to buy 6 more notebooks to meet her requirement of 11 notebooks.

Answer

The answer to the problem is 6.
