Question

Simplify
$1800÷\left[10\left\{\begin{array}{c}(12-6)+(24-12)\end{array}\right\}\right]$

Answer 1

Step 1: Simplify the terms inside {}.
Step 2: Simplify {} and operate with terms outside the bracket.
$1800÷\left[10\left\{\begin{array}{c}(12-6)+(24-12)\end{array}\right\}\right]$
$=1800÷\left[10\left\{\begin{array}{c}6+12\end{array}\right\}\right]$
$=1800÷\left[10\left\{\begin{array}{c}18\end{array}\right\}\right]$
Step 3: Simplify the terms inside [ ].
$=1800÷180$
=10
