# Two numbers with opposite signs are negative of each other.

2022-06-30 By Only two numbers that have the same absolute value and opposite signs are negative of each other.So, two numbers with opposite signs are not necessarily negative of each other.In mathematics, two numbers with the same absolute value and opposite signs are called negative numbers.For example, -1 and 1 are opposites, -1/2 and 1/2 are opposites, the opposite of 0 is 0 (because -0=0), etc.If two numbers are opposites of each other, they must satisfy the following two conditions :(1) the absolute value of each number is the same;(2) The sign is opposite.Two numbers that only satisfy “the same absolute value” can be two equal numbers.And the absolute values of two numbers that only have the opposite sign are not necessarily the same.For example: -2 and 1;1/2 and minus PI and so on.(1) Only two numbers that satisfy the same absolute value and opposite sign can be negative of each other.(2) The absolute values of two numbers that satisfy only opposite signs are not necessarily the same, so they are not necessarily negative of each other.
