  • 1. (9 + 2) x 5 - 5 ) - (-10) : 3
    = 11×5-5 - ((-10):3)
    = 55-5 - (-10/3)
    =50+10/3
    = 150/3+10/3= 160/3 = 53⅓
    2. (35 - 20) x (-4) - 5) : 11
    = (15×(-4)-5) : 11 = ((-60)-5) : 11
    = -65 : 11 = -65/11 = -5 10/11

    3. 50 x (2.714 + 3.537) : (3.391 - 3.373)
    = 50×6.251 : 18 = 312.550 : 18
    = 17367 16/18

    4. 65 x (2.436 - 2.857) : (- 8.636 + 8.657) = 65×(-421) : 21 = -27.365 : 21
    = -1303 ⅔
