Question

(–1) + (–2) = –3 OR (–5) + 2 = –3

Answer 1

Given :


(- 1) + (- 2) = - 3


we know that (+) x (-) = (-)

-1 - 2 = - 3

we know that (-) x (-) = (+)

-1 -2 = - 3.

- 3 = - 3

LHS = RHS.
____________________________


(- 5) + 2 = - 3

-5 + 2 = - 3

we know that (-) x (+) = (-)

-5 + 2 = -3

- 3 = - 3.

LHS = RHS.


Hence : Both Terms are correct.
