Solving Exercise 1 on Page 43 of Math Book 4: Demonstrating the Commutative Property of Addition

Guidance for Solving Exercise 1 on Page 43 of Math Book 4

Problem Statement:
Present the calculated results:

a) 468 + 379 = 847 b) 6,509 + 2,876 = 9,385 c) 4,268 + 76 = 4,344
379 + 468 = 847 2,876 + 6,509= 9,385 76 + 4,268 = 4,344

Solution Method:
* Note: Commutative property of addition: When you change the order of addends in a sum, the sum remains the same.

Answer:
By applying the commutative property of addition, the results of the arithmetic operations can be stated without writing down the calculations as follows:
a) 468 + 379 = 847 b) 6,509 + 2,876 = 9,385 c) 4,268 + 76 = 4,344
379 + 468 = 847 2,876 + 6,509 = 9,385 76 + 4,268 = 4,344

Frequently Asked Questions

What is the commutative property of addition in simple terms?

The commutative property of addition states that changing the order of addends does not affect the sum. For example, 468 + 379 equals 379 + 468, both yielding 847.

How can I demonstrate the commutative property using specific examples?

You can demonstrate the commutative property using examples like 6,509 + 2,876 equals 2,876 + 6,509, both resulting in 9,385, which illustrates that order does not change the result.

What are the results of solving exercise 1 on page 43 of Math Book 4?

The results of exercise 1 are: a) 468 + 379 = 847, b) 6,509 + 2,876 = 9,385, c) 4,268 + 76 = 4,344. Each calculation can also be reordered without changing the sum.

Why is it important to understand the commutative property for future exercises?

Understanding the commutative property is crucial for solving future math exercises as it simplifies calculations, allows flexibility in problem-solving, and builds a strong foundation for more complex mathematical concepts.
