$\large\overbrace{ \underbrace{ \fcolorbox{white}{pink}{ \blue\dag \tt Answer \red\dag}}}$

a) ( -45 ) + ( - 5 )

⟹ - 45 - 5 $\bf [( + ) \times ( - ) = ( - ) ]$

⟹ - 50 $\rm \red {Ans..}$ $[( - ) \times ( - ) =( + )]$

$\rm\red{ [we \: have \: to \: add \: it \: but \: sign \: remains \: same]}$

b) 12(-5) + 5

⟹ -60 + 5

⟹ - 55 $\rm\red{ [The \: no. \: which \: greater \: we \: will \: place \:that \:sign] }$

Some formulas :-

• add × subtract = subtract
• subtract × subtract = add [sign remains subtract]
• add × add = add
