kalau soalnya -25 - 4 x ( - 7 ) = ..... ? hasilnya berapa dan caranya gimana ( 42 + ( - 2 ) : 5 = ..... ? hasil nya berapa dan caranya gimana ( - 8 ) + ( - 8 )

-25 - 4 × (-7)
=>-25 + 28
=> 3

(42 + (-2) : 5
=> 40 : 5
=> 8

(-8) + (-8) : 4
=> -8 - 2
=> -10

219 + (-24) × 27
=> 219 - 648
=> -429

Pembahasan :
-25 - 4 x (-7)
= -25 + [(-4) x (-7)]
= -25 + 28
= 28 - 25
= 3

————————————————
(42 + (-2)) : 5
= (42 - 2) : 5
= 40 : 5
= 8

————————————————
(-8) + (-8) : 4
= -8 + (-8 : 4)
= -8 + (-2)
= -8 - 2
= -(8 + 2)
= -10

————————————————
219 + (-24) x 27
= 219 + (-24 x 27)
= 219 + (-648)
= 219 - 648
= -429
