Hey, there!!
I hope you mean to subtract (-137) +(-43) from sum of -103 and 27.
First, add -103 + 27
{As ( minus + plus )= subtracts with sign which has greator value. }
now,
{ minus + minus = add with minus sign}.
Now, subtracting -180 from -76.
=(-76) - (-180 )
Now, multiply the sign (- × -)= +
so, -180 becomes +180
= -76+180
= 104..... is answer.
Hope it helps...
