Question

Evaluate the following expression.
$75-\left\{\right(25÷5)+7\}$

Answer 1

$75-\{\underset{–}{(25÷5)}+7\}\Rightarrow$ Simplify the terms in the innermost parentheses first, as per the order of operations, MDAS.
$=75-\left\{\underset{–}{5+7}\right\}\Rightarrow$ Simplify the terms in the curly braces next, again, following the order of operations, MDAS.
$=\underset{–}{75-12}\Rightarrow$ Perform addition or subtraction, whichever appears first from left to right.
$=63$
