x^-1 * x^-1 =x^(-1 + -1) =x^-2 or alternatively: 1/x times 1/x =1/x^2 (1/x^2) is the same as (x^-2)
When a negative number is raised to an even power, the result is always positive. Therefore, (-1)^4 equals 1. This is because multiplying a negative number by itself an even number of times will always result in a positive value.
1/3 x -2 = -2/3

The answer is "negative three halfs." (- 3/2) or _ 1 1/2 The equation is: -2/3 (x) = 1 -x = 3/2 x = -3/2 (aka negative one and one half)

-1/2 X -2 = -- 2/2 = (+) 1 = 1
negative 2 over 6

negative two-thirds
2 x -2 - 3 x 3 + -1 = (2 x -2) - (3 x 3) + (-1) = -4 - 9 - 1 = -14.
2 * (-2) - (-5) = 1
-9/2
+1/2
2-1 x 2-2 = 2-1 + -2 = 2-3 = 1/8, or one eighth.
Negative times negative is positive. Negative 2 times negative 2 equals positive 4.
x^-1 * x^-1 =x^(-1 + -1) =x^-2 or alternatively: 1/x times 1/x =1/x^2 (1/x^2) is the same as (x^-2)
