Let A be 30° 
and B be 60°

   Sin(A+B)
= Sin(30°+60°)
= Sin90° 
= 1 ---------------(1)

   SinA + SinB
= Sin30° + Sin60°
= 1/2 + (√3)/2
= (1+√3)/2  -----------(2)

(1) is not equal to (2)
∴ It is not right to say that Sin(A+B)= Sin A + Sin B

Yes sin A+sin B =sin (A+B)

it is wrong to say that way
they are not equal
