Nếu \[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} {\rm{f}}\left( {\rm{x}} \right){\rm{ = L}},\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} {\rm{g}}\left( {\rm{x}} \right){\rm{ = M}}\]thì:

\[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} \left[ {{\rm{f}}\left( {\rm{x}} \right){\rm{ + g}}\left( {\rm{x}} \right)} \right] = {\rm{L + M}}\].

\[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} \left[ {{\rm{f}}\left( {\rm{x}} \right){\rm{ + g}}\left( {\rm{x}} \right)} \right] = {\rm{L }}{\rm{. M}}\].

\[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} \left[ {{\rm{f}}\left( {\rm{x}} \right){\rm{ + g}}\left( {\rm{x}} \right)} \right] = {\rm{L}} - {\rm{M}}\].

\[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} \left[ {{\rm{f}}\left( {\rm{x}} \right){\rm{ + g}}\left( {\rm{x}} \right)} \right] = {\rm{L}} + 3{\rm{M}}\].

Giải thích

\[\mathop {\lim }\limits_{{\rm{x}} \to {{\rm{x}}_0}} \left[ {{\rm{f}}\left( {\rm{x}} \right){\rm{ + g}}\left( {\rm{x}} \right)} \right] = {\rm{L + M}}\].
