What is the value of $$[7\div14\times8+(5\div15\times6-4\times3)]$$?
=Â $$[7\div14\times8+(5\div15\times6-4\times3)]$$
= $$\left[\frac{7}{14}\times8+\left(\frac{5}{15}\times6-4\times3\right)\right]$$
=Â $$\left[\frac{1}{2}\times8+\left(\frac{1}{3}\times6-4\times3\right)\right]$$
= $$\left[4+\left(2-12\right)\right]$$
=Â $$\left[4-10\right]$$
= -6
