The rules for division are exactly the same as the rules for multiplication.
* Division (or multiplication) of a positive number by a positive number = positive
* Division of a positive number by a negative number = negative
* Division of a negative number by a positive number = negative
* Division of a negative number by a negative number = positive
If you have trouble remembering any of these, just try out a sample division on any calculator - for instance, if you divide (-1) / (-1) you get +1.

How do you estimate a percentage when the denominator is a negative number?
Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.

Multiplication or division of two numbers of opposite signs: negative*positive, positive*negative, negative/positive, and positive/negative. Addition of two negative numbers: -5 + -2 = -7 Multiplying pure imaginary numbers of the same 'sign' : 5i * 2i = -10. -3i * -4i = -12. Dividing pure imaginary numbers of different signs (this comes from the fact that 1/i = -i, and i/i = +1)
How do you divide a negative fraction by a negative fraction?
-- Ignore the signs. -- Divide the first fraction by the second fraction, then decide whether the answer is positive or negative. -- If both numbers in a division have the same sign, then the quotient is positive. So the quotient is positive, and you're done.
