Question

(–9) – (– 4) = –5 or (–2) – 3 = –5

Answer 1

2nd one is correct.....
(--2)-- 3=---2--3 = --5
...(-- n -- becomes + so we will add but its not multiplication or division so sign wont change .... bot are negative so negative sign shud be there)

1st answer is also correct....
(--9)--(--4)= --9 +4= 5....

Answer 2

(- 9) - (- 4) = - 5

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

-9 + 4 = -5

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

- 5 = -5

LHS = RHS

____________________________

(- 2) - 3 = - 5

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

-2 -3 = -5

- 5 = - 5

LHS = RHS .


Hence : Both Terms are correct.
