![]() If you have a positive and a negative, there is one dash left over, and the answer is negative. When you have two negative signs, one turns over, and they add together to make a positive. Two negatives cancel out and make a positive, in maths as well as in speech. “Don’t not do it” means “please do it”.“Don’t do that!” is asking someone not to do something.“Just do it!” is a positive encouragement to do something.By facing in the negative direction, and walking backwards ( two negatives), you have achieved a positive result. Now take two steps backwards, and then another two backwards. Finally, back at zero again, face in the negative direction.A positive (the direction you are facing) and a negative (the direction you are moving) result in a negative move. Face the positive direction again and take two steps backwards. ![]()
