NO!!!
Squaring a negative number is a positive answer.
-a X -a (+)a^2
Remember the table for multiplying negative/positive numbers.
X + = +
X - = -
X + = -
X - = +
If no sign is given , readf it as positive(+)/.
Yes
Squaring. Doubling is only multiplying a number by 2, whereas, squaring is multiplying a number by itself :)
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.
Squaring a number means multiplying it by itself. For example, squaring the number 5 means multiplying 5 x 5.
Squaring a number in math is basicly multiplying a number by itself such as... 3^2= 3*3=9 or 3^3=3*3*3=27 ^= the squared number *= multiplication I hope this information was useful.
That is also called "squaring the number", or "raising the number to the second power".
If you square any real number it will always be positive.
Yes on some calculators it will make a difference.
Then the answer becomes 4, the fact that you are squaring a negative number makes the result positive.

No The test statistic F-Test is a sum of squares, which by definition of squaring a number it must be positive.
Taking a number to the second power is known as "squaring" the number.
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.
Squaring a number means multiplying it by itself. For example, squaring the number 5 means multiplying 5 x 5.
Squaring is a number raised to the power of two. Scientific notation is a number multiplied by 10 to the power of a number.
Taking the square root of a negative number is not the same as squaring a number because the square root is only defined for non-negative numbers. Additionally, taking the square root of a non-perfect square number will result in an irrational number, which cannot be expressed as a fraction or a repeating decimal.
squaring a number is when you times it by itself. eg. 2x2 or 5x5 cubing a number is when you times it by itself and then times it again. eg. 2x2x2 or 5x5x5
