Question

(-8)+(-12)=(-12)+(-8)

Answer 1

Answer:

-20

Step-by-step explanation:

-8 + -12 = -12 + -8

The addition symbols can be cancelled.

now negative 8 minus 12 is -20

and negative 12 minus 8 is also -20

therefore they are equal and the value is negative 20

Answer 2

Step-by-step explanation:

$( - 8) + ( - 12) = ( - 12) + ( - 8)$

$- 8 - 12 = - 12 - 8$

$- 20 = - 20$

LHS = RHS
