  • 800 - 900 + 650 x (-8) : 130 = 800 - 900 + (-5.200) : 130
                                                 = -100 + (-40)
                                                 = -140

    1800 : (-45) x 35 - 40 x 45 = -40 x 35 - 40 x 45
                                               = -1400 - 1800
                                               = - 3200
                                              
    25 x 90 + 4500 : (-9) + (-16) x 60 = 2.250 + (-500) + (-960)
                                                         = 2.250 - 500 - 960
                                                         = 790
  • 800 - 900 + 650 × (-8) ÷ 130 = 800 - 900 (( 650 × (-8)) ÷ 130 = 800 - 900 - 5200 ÷ 130 = 800 - 900 - (5200 ÷ 130) = 800 - 900 - 40 = -100 - 40 = - 140

    1800 ÷ (-45) × 35 - 40 × 45 = ((1800 ÷ (-45)) × 35 - 40 × 45 = -40 × 35 - 40 × 45 = -1400 - (40 × 45) = -1400 -1800 = -3200

    25 × 90 + 4500 ÷ (-9) + (-16) × 60 = 2250 + 4500 ÷ (-9) + (-16) × 60 = 2250 - 500 + (-16) × 60 = 2250 - 500 - 960 = 1750 - 960 = 790
