"The product of any two even integers is a multiple of 4."

My proof seems to be going in circles! Any guidance would be amazing!

In summary, an even integer is a whole number divisible by 2 with a remainder of 0. When two even integers are multiplied, the product will always be a multiple of 4 because the even numbers are essentially multiplied by 2 twice. This concept holds true for any two even integers, regardless of their size, and can be applied in fields such as engineering, computer science, and physics for efficient division and calculating forces and energy in systems with multiple even integers.

Hi nastygoalie89! Welcome to PF!

Start "Let the integers be 2a and 2b …"

An even integer is any whole number that is divisible by 2, resulting in a remainder of 0.

This is because when you multiply two even integers, you are essentially multiplying 2 to an even number twice. Since 2 multiplied by an even number always results in an even number, multiplying by 2 twice will result in a number that is divisible by 4.

Sure, let's take the even integers 4 and 6. When we multiply them, we get 4 x 6 = 24. Since 24 is divisible by 4, it is a multiple of 4.

Yes, this concept holds true for any two even integers. Whether the integers are small or large, their product will always be a multiple of 4 as long as they are both even.

This concept can be applied in various fields such as engineering, computer science, and physics. For example, in computer science, it is used in algorithms for efficient division and in physics, it is used in calculating forces and energy in systems with multiple even integers.
