1)...
a - (b - c) = (a + c) - b
a - b + c = a + c - b
a - b + c = a - b + c ✔️ TERBUKTI
2)...
-a / b : (- c) = a / c : (b)
-a / b × 1 / - c = a / c × 1 / b
-a / -cb = a /cb
a / cb = a /cb ✔️ TERBUKTI
3)...
- abc / - klm = a / k . b / l . c / m
abc / klm = a / k . b / l . c / m
abc / klm = abc / klm ✔️TERBUKTI
4)...
(a - b) : (- c) = (b : c) - (a : c)
a - b / - c = b / c - a / c
b - a / c = b - a / c ✔️TERBUKTI
5)...
a - b = ( a - c ) - ( b - c )
a - b = a - c - b + c
a - b = a - b + c - c
a - b = a - b ✔️ TERBUKTI
Semoga membantu kak ^_^
