  • 1. 2.500 + (-50 : -10) x -5 = 2.500+ 5 x (-5)
    =2.500 - 25
    = 2475
    2. -2000-(-15) x (-5)
    = -2000 + 15 x (-5)
    = -2000 - 75
    = -2075
    3. -25 x (-18 x -5) + 2000
    = -25 x 90 + 2000
    = 2250 + 2000
    = -250
    4. -18 + (-100 : -25) x 15
    = -18 + 4 x 15
    = 42
    6. -15 x -20 + (100 x -4)
    = 300 + (100 x (-4))
    = 300 + (-400)
    = 300 - 400
    = -100
    7. 25 x -4 + (150 : 15) + 12
    = -100 + (150 : 15) + 12
    = -100 + 10 + 12
    = -78
    8. -6000 + 4000 - (25 : -4)
    = -6000 + 4000 - (-6,25)
    = -6000 + 4000 + 6,25
    = -1993,75
    9. 7500 - 9000 + (-60 : -15) + 100
    = 7500 - 9000 + 4 + 100
    = -1396
    10. -10.000 + 9000 - (25 x -10)
    = -10.000 + 9000 - (-250)
    = -10.000 + 9000 + 250
    = -750
    Maaf cuma segitu aja
