Why does minus minus a minus equal a minus?

Minus minus a minus does not necessarily produce a minus answer.Here is an example of a minus figure, minus another minus figure:-3 - (-5) = -3 + 5 = +2As long as the absolute value of the first number is smaller than that of the second, the final answer will always be positive.If the two are equal, the final answer is 0:-4 - (-4) = -4 + 4 = 0Only if the magnitude of the first is larger than the second is the answer negative: -3 - (-2) = -3 + 2 = -1-------------------------------------------------------------------------------------------------------HOWEVER, if we are trying to determine the sign of a number that has multiple signs, for example (-3), -(-3), or -(-(-3)), [minus, minus a minus] then the logic is this:A negative is a negative, so -3 is negative, and means deduct 3A negative negative is a positive, so -(-3) is positive and means add 3A negative 'negative negative' is a negative, so -(-(-3)) [i.e. minus, minus a minus] is negative and means minus 3Let's work it through another way:If minus n means minus nThen minus (minus n) must mean plus nTherefore minus (minus (minus n)) must mean minus nYet another way to think of it:If you add a minus figure to a calculation, you deduct it.But if you deduct a minus figure, you must ADD it (thereby reversing its original 'negativity' and the figure become a positive one)So if you have to then 'minus' it once more, (thereby reversing its positive status) it has 'minus' value again.Method of determining the signIf you have a formula with 'stacked' minuses, remove them in pairs, starting from the left. If you've got one left, the resulting value will be a minus figure. But if 'pairing' them removes them all, then the remaining figure is positive, i.e. '+'.


Does a negative number minus a positive number equal a positive?

The simple answer to the question is no, under no circumstances. To work out the right answer for different combinations of signs, read on. When two signs are different, take the smaller number from the bigger number and keep the sign of the bigger number.Let's work out some examples...* minus one (-1) and (plus) another minus one, is minus two (-2) * minus one (-1) minus (take away) one, is also minus two (-2)So if you take away any positive number from a negative number, the result gets more and more negative as the value of the second number increases. Now let's try adding a positive number to a negative number...* minus two (-2) plus one (+1) = minus one (-1) * minus two (-2) plus two (+2) = zero (0) * minus two (-2) plus three (+3) = one (1)So adding a positive number to a minus number only equals a positive number when the value of the positive number is greater than the negative number.

Divide the nine by three. Thus: 9 ÷ 3 = 3


What is the square rute of 9?

The square root of 9 is the number which, when multiplied by itself, equals nine. There are two numbers which, when squared, equal nine: positive three and negative three. Depending on the context of the question, one of the numbers may not make sense as an answer, or they both may work as answers.

What does negative 2 fivehteenths minus negative 1 ninth equal?

I work it out like this: (-2/15) - (-1/9) = (-2/15) + (1/9) ) [minus negative is the same as plus] = (-6/45)+(5/45) [change both to 45th as that is the lowest common multiple of 15 and 9] =-1/45 or negative1/45


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.
