Does 1 x -1 equal 0 or 1? and plz explain!?

Answer 1

no.
1 x -1 = -1
-1 x 1 = -1
0 x anything is 0
-1 x -1 = 1
-1 x -1 x -1 = -1
-1 x -1 x -1 x -1 = 1
When multiplying a positive number times a negative number, the result is negative.
When multiplying a negative number times a negative number the result is positive. It accumulates because multiplication is associative.

(-1 x -1) x-1 is the same as (1) x -1 = -1
-1 x (-1 x -1) is the same as -1 x (1) = -1

Answer 2

It equals negative 1.

Answer 3

it equals -1. adding the two number would be 0. any positive number multiplied by a negitive number will give you a negitive number. Also any negative number * a negative number is a positive number. -1 * -1 = 1

Answer 4

Depends on what you set it equal to.

1x -1 = 0
1x = 1
x = 1
Hence, if 1x -1 = 0, x must 1 because 1(1) - 1 is the only way to get 0.

The expression 1x -1 isn't equal to anything because it has no '=' sign, hence, your question might need to be rephrased.

Answer 5

neither. it equals -1. a positive times a negative equals a negative. any number times 1 is that number. so, 1x-1=-1

Answer 6

-1... because if you have a postive and a negitive number, the postive with take the opposite number's sign. -1 x -1 would equal +1.

Answer 7

1*-1=-1 a negative and a positive make a negative, a negative and a negative make a positive, a positive and a positive make a positive.

Answer 8

Watchmaker analogy--debunked too many situations to even recount. "on the time whilst the Qur’an replaced into printed, human beings theory the international replaced into flat" incorrect, the classic Greeks knew the earth replaced into around even in the previous the time of Christ. "the sunshine of the moon could be its very own easy or a meditated easy" No divine perception required to confirm that the moon is meditated easy. Any lifestyle that practiced even the main primitive astronomy at as quickly as concluded that the moon replaced into meditated easy. "the recommendations are say approximately 10,000" no longer in elementary terms is that extensive type thoroughly arbitrary, despite the fact that it extremely is outrageously extreme, and for this reason your declare of a million/10,000 is meaningless. in fact historic cultures believed each and everything replaced into composed of various ratios of four aspects: air, earth, wind and water, and the remark that people leaked once you poked a hollow in them could clearly deliver approximately an assumption that water replaced into the dominant ingredient. So your argument fails at each and every turn.

Answer 9

it equals -1. a negative number times a positive number is negative, and to multiply you ignore the positive or negative and multiply them like they are both positive, so 1x1=1, and since one of them is negative, the answer is negative. negative times negative is positive, negative times positive is negative.

Answer 10

if the x is multiply then 1 x -1 = negative 1 or -1

if x is alphabet then i dont know
