Step-by-step explanation:

${\huge{\textbf{\fbox{\textsf{\color{navy}{༒An}}{\purple{sw}}{\pink{er༒}}}}}}$

${\bold{\sf{ 21 \: x \: (-13 \: + \: 12)}}}$

${\bold{\sf{\fbox{\pink{Let's apply BODMAS on above mentioned expression}}}}}$

${\bold{\sf{\underline{BODMAS :-}}}}$

${\bold{\sf{B \: = \: Bracket}}}$

${\bold{\sf{O \: = \: Of}}}$

${\bold{\sf{D \: = \: Division}}}$

${\bold{\sf{M \: = \: Multiplication}}}$

${\bold{\sf{A \: = \: Addition}}}$

${\bold{\sf{S \: = \: Subtraction}}}$

$\\ {\bold{\sf{\underline{Through \: \: this \: property \: we \: have \: to \: solve \: bracket \: first}}}}$

${\bold{\sf{21 \: x \: (-13 \: + \: 12)}}}$

${\bold{\sf{→ \: 21 \: × \: (-1)}}}$

${\bold{\sf{→ \: -21}}}$
