Why does negative 2 squared equal negative 4?

Answer 1

Because negating a positive number gives a negative number, and squaring any number is always positive.

22 = 4

→ -(22) = -(4) = -4.

But note:

(-2)2 = 4 ≠ -4.

It is very important that when giving your question you are clear to where the negative is attached.

Answer 2

In mathematics, when we square a number, we multiply it by itself. So, when we square -2, we are calculating (-2) x (-2), which equals 4. However, since we started with a negative number, the result maintains the negative sign, giving us -4. This is due to the rules of arithmetic and the properties of multiplication of negative numbers.

Answer 3

Oh, dude, negative 2 squared equals negative 4 because when you square a negative number, you're basically multiplying it by itself, and two negatives make a positive... just kidding, they actually make a negative! So, negative 2 times negative 2 equals positive 4, but since we started with a negative 2, it stays negative, resulting in negative 4. It's like math's way of playing a little prank on you.

Answer 4

Oh, honey, negative 2 squared equals positive 4, not negative 4. When you square a negative number, it becomes positive. It's like turning that frown upside down!
