If $\left\{\begin{matrix} \text{“} \oplus\text{”} \; \text{means}\; \text{“}-\text{”} \\  \text{“} \otimes\text{”} \; \text{means}\; \text{“}\div\text{”}  \\  \text{“} \triangle\text{”} \; \text{means}\; \text{“}+\text{”}  \\  \text{“} \triangledown\text{”} \; \text{means}\; \text{“}\times\text{”}  \end{matrix}\right.$

then, the value of the expression $\triangle 2 \oplus 3 \triangle \left((4 \otimes 2) \triangledown 4) \right) = $

  1. $-1$
  2. $-0.5$
  3. $6$

The value of the expression $\triangle 2 \oplus 3 \triangle \left((4 \otimes 2) \triangledown 4) \right) = +2 -3+((4\div 2) \times 4)  = -1 + 8 = 7.\quad$

So, the correct answer is $(D).$
