Raising a product to a power exponent rule?
power of 0
When adding a positive number to a negative number what is a good rule for determining the sign of the sum?
If the negative number is a bigger number, the answer will be negative. Conversely, if the positive number is bigger, the answer will be positive. -20+10= -10 (larger negative number) -10+20=10 (larger positive number)
What is the general rule for multiplying a decimal by a negative integer power of 10?
The decimal point is moved to the left by the value of the power.
What is the rule for a number multiplied by the power of zero?
Anything to the zero power equals one.
What is the rule for adding 2 negative integers?
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
What is a rule for raising a negative number into a power number?
The answer depends on the power number. If, for example, the power number is -0.5, then there is no rule in real numbers.

Why does a negative integer raised to an even power always result in a positive integer?
The multiplication rule of thumb always states that a negative number times a negative number results in a positive number. Since an even number is always divisible by two, any value raised to an even integer power will result in a positive number. However, a basic proof is presented as follows: (-A) * (-A) = A^2 ((-A) * (-A)) ^ 2 = ((-A * -A) * (-A * -A)) = A^2 * A^2 = A ^ 4 ...

What is the rule for subtracting negative numbers?
e.g. 'a' - ( -a) becomes a -- a a + a = 2a Here with a table for manipulating 'double' signs. = + = - = - = + NB If no sign is shown in front of a number , then read the number as plus(O).
