This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.]]> 2016-09-16 14:05:58 UTC https://padlet.com/giko2605/ashpo4r8279b/wish/124350464
