Such that 155 = 759375, 15-5 = 1/759375

negative 0.0016
negative 5 or -5
3
It is: 1/3 of -15 = -5
It is equivalent to 1 over 5 to the power of 5, or 1 over 3125.
Negative 5 is greater. - 5- (-10) = 10
-15-(-10)= -15+10= -5
5 - (-15) = 20
-20 -(-5) = -15 ie -(-5) = +5 therefore -20 +5 =15 (two double minuses = a positive)
3(-5)=-15 *negative
Negative 5 to the second power would be -5 times -5 which would be 25.
