Answer 1

Răspuns:

a) 610:5+5x[12x6-4x11-8]:100+13

610:5+5x(72-44-8):100+13

610:5+5x(28-8):100+13

610:5+5x20:100+13

122+100:100+13

122+1+13=136

b) 17+3x[4x(22+54:6)-55]

17+3x[4x(22+9)-55]

17+3x(4x31-55)

17+3x(124-55)

17+3x69

17+207=224

c)( 29x14-29x4)+12x11+8x{125-5x[340-2x(22x19-23x11)]}

(406-116)+12x11+8x[125-5x[340-2x(418-253)]

290+12x11+8x[125-5x(340-2x165)]

290+12x11+8x[125-5x(340-330)]

290+12x11+8x(125-5x10)

290+12x11+8x(125-50)

290+12x11+8x75

290+132+600=1022

d)

23+7x{41+4x[3+8x(11x12-8x10)-59]}+1002

23+7x{41+4x[3+8x(132-80)-59]}+1002

23+7x[41+4x(3+8x52-59)]+1002

23+7x[41+4x(3+416-59)+1002

23+7x[41+4x(3+357)+1002

23+7x(41+4x360)+1002

23+7x(41+1440)+1002

23+7x1481+1002

23+10367+1002

10390+1002=11392
