ǫᴜᴇsᴛɪᴏɴ :

Nomor 7 dan 9

ᴀɴsᴡᴇʀ :

7. 391

9. –561

ᴇxᴘʟᴀɴᴀᴛɪᴏɴ :

7. ( -1.010 ) + 732 – ( -428 ) + 241 =

= -1.010 + 732 = – ( 1.010 – 732 ) = –278

= -278 – ( -428 ) = 150

= 150 + 241 = 391

= 391

9. ( -1.400 ) – 192 + 785 – ( -246 ) =

= -1.400 – 192 = – ( 1.400 + 192 ) = –1.592

= -1.592 + 785 = – ( 1.592 – 785 ) = –807

= -807 – ( -246 ) = – ( 807 – 246 ) = –561

= –561
