Tell this to M. Scott: 2 + 2 = 2 - (-2) = -(-2 - 2) = 4
But I'm glad you got it.
As for Ma Kaali (Mother Kaali)... that's cool... but remember... she's not all death and gloom... she's ultimately the Mother... like all Mothers, she can be the apogee of care and love (Bhadra Kaali/Gentle Kaali) or a scary force to be reckoned with, even unreasonable (Smashaan Kaali/Crematorial Kaali). But she is pretty freaky... I love her.
