If you mean (5*10)^-1 that is 1/50
If you mean 5*10^-1 that is 1/2
1*10^-5 = 1/100000 or 0.00001
Positive minus a negative = positive plus a positive two negatives make a positive 3- (-1) = 3 + 1 = 4 5- (-7) = 12
10
No, a negative x a negative = a positive. (-5) x (-2) = 10
x*(-5) = 10 Divide both sides by 5: x*(-1) = 2 Multiply both sides by -1 and remember that (-1)*(-1) = +1 x*(+1) = -2 x = -2

-5 x 10 = -50
negative times a negative is positive. (- x - = +) Ex., -2 X -5 = 10
1 x 101 = 10 1 x 100 = 1 1 x 10-1 = 0.1 1 x 10-2 = 0.01 1 x 10-3 = 0.001 1 x 10-4 = 0.0001 1 x 10-5 = 0.00001 1 x 10-6 = 0.000001 1 x 10-7 = 0.0000001 1 x 10-8 = 0.00000001 1 x 10-9 = 0.000000001 1 x 10-10 = 0.0000000001
256-5 = 1/2565 = 9.094947 x 10-13 approximately,
5 x -2 = -10
-10 x -5 = +50A negative times a negative will always equal a positive number.A negative times a positive will always equal a negative number.A positive times a positive will always equal a positive number.- x - = +- x + = -+ x + = +
