Rules for Positive and Negative Numbers | Advance

In this named "Rules for Positive and Negative Numbers Advance", we have used mathematical expressions (more than two numbers) and implemented for Add/Subtract and Multiply/Divide the Numbers having different sign and explained it with multiple examples. As we know that some student feel Math very boring/irritating subject. Because they cannot understand a basic arithmetic rule of Add/Subtract and Multiply/Divide of two Numbers having different sign or similar sign. If they understand this rule then math can be an enjoyment and a magic for them, otherwise irritation/frustration.
