If A is an operation such that for integers m and n, we get\[\mathbf{m}\text{ }\Delta \text{ }\mathbf{n}\text{ }=\text{ }\mathbf{m}\text{ }\mathbf{x}\text{ }\mathbf{m}\text{ }\mathbf{x}\text{ }\mathbf{m}+\mathbf{n}\text{ }\mathbf{x}\text{ }\mathbf{n}\text{ }\mathbf{x}\text{ }\mathbf{n}-\mathbf{3}\text{ }\mathbf{x}\text{ }\mathbf{m}\text{ }\mathbf{x}\text{ }\mathbf{n}\], then find\[\left( -\text{ }\mathbf{4} \right)\text{ }\Delta \text{ }\mathbf{5}\]. |
