Why does two times two equal four AND two plus two equal four?

Answer 1

In arithmetic, multiplication of one number, a, by another, b, consists of adding a to itself btimes. The identity element for arithmetic multiplication is 1, meaning that a number multiplied by 1 is still that number.

So, a x b = 2 x 2 = 2 added to itself 2 times = 2 + 2 = 4.

Other examples:

2 x 1 = 2

2 x 3 = 2 + 2 + 2 = 6

3 x 4 = 3 + 3 + 3 + 3 = 12

3 x 3 = 3 + 3 + 3 = 9

4 x 2 = 4 + 4 = 8

4 x 5 = 4 + 4 + 4 + 4 + 4 = 20

Answer 2

In mathematics, multiplication and addition are two different arithmetic operations that follow distinct rules. When we multiply two by two, we are essentially adding two groups of two together, resulting in a total of four. Similarly, when we add two and two, we are combining two individual quantities to get a sum of four. Both operations ultimately lead to the same numerical value of four due to the fundamental principles of arithmetic.

Answer 3

Oh, dude, it's like this weird math thing called addition and multiplication. So, when you add two and two, you get four because, like, that's just how addition works. And then, when you multiply two by two, you also get four because, like, that's how multiplication rolls. It's like math being all consistent and stuff, you know?
