A positive times a positive equals a positive, a negative times a negative equals a positive, a negative times a positive equals a negative(vice versa for the last one)

How would you explain to a seventh grader the difference between the domains of an odd root radical function and an even root radical function?
To start with, when you multiply an even number of negative numbers, the answer is positive. When you multiply an odd number of negative numbers, the answer is negative. When you multiply any number of positive numbers, the answer is always positive. For positive numbers, the value of a power is always positive. For negative numbers, the value of an odd power is negative, and the value of an even power is positive. Finding roots is the inverse of taking powers, so that an odd-root function can be evaluated for any value of x. An even-root function, however, cannot be evaluated when the value of x is negative, since an even power can never result in a negative answer. The domain of an odd root function is all real numbers; the domain of an even root function is the non-negative real numbers.
Can you show on a number line how subtracting a negative number ends up positive?
-3...-2...-1...0...1...2...3To find the positive number when subtracting from a (-)number is finding the Absolute Value of the sum. Another way is changing the negative number to a positive and reversing the equation.*Such as, 1-(-3)--> +3-1. So than the answer is a positive 4.* Dots represent the actual line

How do you you reduce a fraction with a negative number as a numerator?
To reduce a fraction with a negative number as a numerator, you can first simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator. Then, divide both the numerator and denominator by their GCD and the negative sign remains unchanged. This will result in a reduced fraction with a negative numerator.
What is the trick to finding the least common multiple?
Prime factor tree!
Can the error be positive or negative in finding relative error?
Yes.
What are all the multiples of negative numbers?
The same way as finding factors of positive numbers but the answer includes both the positive and negative factors.
How can you tell whether the sum of 71 and 43 is a positive or negative without actually finding the sum?
The sum of two positive numbers is always positive.
How do you know when the slope of a line is negative?
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.
What are the positive and negative referred to?
When used with numbers, positive means "more than zero", and negative means "less than zero". Other meanings are:* Positive: something favorable; negative: something unfavorable. * Positive: something is found; negative: nothing was found. Especially used for medical analysis. Note that this meaning is quite contrary to the previous one - since finding a disease can be quite unfavorable for the patient!
What is the difference between finding a factor and finding a multiple?
a factor is what you multiply by a multiple is the answer
Can you find an answer to a question you do not know?
The answer to any question must be positive or negative. Therefore one has a 50-50 chance of finding the correct answer to a question one does not know. By presenting a positive or negative answer at random to the unknown question, one has an edge over finding the unknown question. By using the given answer as a guide the question, in question, will arrive momentarily consequential to some thought regarding the answer that has no question, Simple!!
