$- 360$ $-360$

Count the number of terms first. There is only one term.

Count the number of terms inside the parentheses,
There are 2 terms.
Simplify each term separately. Calculate inside the parentheses first.

= $8 [- 5 + 8 (- 7 + 2)]$ $8[color(blue)(-5) +8 color(magenta)((-7 + 2))]$

= $8 [- 5 + 8 (- 5)] now multiply$ $8[color(blue)(-5) + color(magenta)(8(-5))] " now multiply"$

= $8 [- 5 - 40] calculate inside the parentheses$ $8[color(blue)(-5) color(magenta)(-40)] " calculate inside the parentheses"$

= $8 [- 45] now do the final multiplication$ $8[color(orange)(-45)]" now do the final multiplication"$

= $8 \times - 45 = - 360$ $8 xx -45 = -360$
