It's saying subtract a negative number, so take away from something that negative is adding something positive.
Think about it like this, If you have a number 5, and someone says to you take away from 5 negative 2, you'd have 7. If what you subtract from something is negative, you gain.
I know it may not make sense, but think about it for a bit and I'm sure you'll get it, if not, just remember to do it when you're doing your work.
There is no such thing as a positive or a negative zero. A negative divided by a positive is a negative, and a positive divided by a negative is a negative. If you have a negative and a positive, the answer will be a negative. But if you have two negatives or two positives as the dividend and divisor, the answer will be a positive. In other words, dividing two positives or two negatives will always give you a positive. But dividing a positive and a negative will always give you a negative.
The best way to figure this out would be to use an example. So suppose you had a -20 and divided that by a positive 5. That would give you a -4. Take that -4 and divide it by a -2 which would give you a positive 2 (knowing that two negative numbers cancel out to make a positive number). Thus a negative divided by a positive divided by a negative would give you a positive number.
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.
A positive number divided by a negative number, or vice versa, will give you a negative number.
Multiplying a positive and negative number will give a negative result. The result is a negative number.

If you multiply two positive numbers, or two negative numbers, the result will be positive.If you multiply a positive and a negative number, the result will be negative.The same rules apply for division - a positive number divided by a negative number, or a negative number divided by a positive number, will give a negative result.In any case, most of the calculation is the same as for positive numbers - you only have the additional complication of deciding whether to put a plus sign or a minus sign in front of the result. For example, -8 / 2 = -4; the absolute value (4) is the same as when you divide 8 / 2, only the sign changes.If you multiply two positive numbers, or two negative numbers, the result will be positive.If you multiply a positive and a negative number, the result will be negative.The same rules apply for division - a positive number divided by a negative number, or a negative number divided by a positive number, will give a negative result.In any case, most of the calculation is the same as for positive numbers - you only have the additional complication of deciding whether to put a plus sign or a minus sign in front of the result.

A negative number. For example, -4/2=-2
2 negatives equal a positive or if you multiply a negative by a positive it is larger negative if you multiply a negative and a negative it become positive because doing something negative times is getting bigger
A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.A negative number times a positive number will give you a negative product.
Pretend the negative number is positivedivide the positive number by a positive numbermake the result negative.For example, divide 12 by -6:Pretend -6 is 6divide 12 by 6 to get 2make the result negative to give -2Thus 12 ÷ -6 = -2
The answer to this depends on what you are doing with the numbers..... * A negative added to a negative gives a negative (-3) + (-5) = -8 * A negative subtracted from a negative may give either a negative or a positive (-3) - (-5) = +2 (-5) - (-3) = -2 * A negative multiplied by a negative gives a positive (-3) x (-5) = +15 * A negative divided by a negative gives a positive (-3) ÷ (-5) = +0.6
No, it does not.
