True or false is a number minus its opposite is twice the number?
True
What is the difference between the square of a number and twice the number?
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
Is a cube a number multiplied by itself twice?
no its when its multiplied by itself 3 times for instance 33 is 3x3x3 which is 27.
What number when multiplied by itself twice is 225?
To find the number that, when multiplied by itself twice, equals 225, you need to find the square root of 225. The square root of 225 is 15. Therefore, the number you are looking for is 15. When you multiply 15 by itself twice (15 x 15 x 15), you get 225.

You would need to divide by -1/2.

How can you prove that a perfect number can never be a prime number?
In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.

What number added itself to make 18?
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
What is the cube of a number?
A cube of a number is when you multiply it by itself twice. Eg) 2 cubed = 2x2x2=8
What is the definition of opposite numbers?
The additive opposite of a positive is a negative, and the opposite of a negative is a positive. If you reverse the sign twice (opposite of opposite) you have the original number. The same applies to an inverse (multiplicative opposite): the inverse of any inverse for a nonzero number is the original number. n (1/n)(n) = n
