66

$-2/3[-10+8-64]$

$-2/3[-2-64]$

$-2/3[-66]$

$(-2/3)xx(-66)$

But a minus times a minus is plus answer so we have:

$color(blue)(2/3xx66)$

But you can write $color(blue)(2/3xx66)" as "color(brown)( 2xx66/3)$

but $" "66/3=33$

so $color(brown)( 2xx66/3)" "$ can be written as $" " 2xx33$

$" "2xx33=66$
