Question

What is the value of the given expression?
$\left[\right[3\times \left\{\right(-5)\times (-4\left)\right\}]÷\{27+(-13-4\left)\right\}]$
$+[\{27\times (-2\left)\right\}÷(-3-3\left)\right]$
$+[\left\{\right(-3)\times (-3)\times 5\}÷(-3\left)\right]]$

• A. 0
• B. 1
• C. -1
• D. 13

Answer 1

The correct option is A

0

$\left[\right[3\times \left\{\right(-5)\times (-4\left)\right\}]÷\{27+(-13-4\left)\right\}$
$+[\{27\times (-2\left)\right\}÷(-3-3\left)\right]$
$+[\left\{\right(-3)\times (-3)\times 5\}÷(-3\left)\right]]$

$=\left[\right[3\times \left\{\right(20\left)\right\}]÷\{27+(-17\left)\right\}]$
$+[\{-54\}÷(-6\left)\right]$
$+[\{9\times 5\}÷(-3\left)\right]]$

$=\left[\right[60]÷\left\{10\right\}]$
$+\left[9\right]$
$+[\left\{45\right\}÷(-3\left)\right]$

$=\left[6\right]+\left[9\right]+[-15]$

$=15-15$

$=0$
