Answer 1

№1 (-8 - 2 -14) : 6 +8 -3= -24 :6 +8-3= -4 +8-3=1

№ 2 4 - 48: (-6 3 - 6) - 20= 24 - 48 : (-69) -20= 24 +16/23-20=4 +16/23=4 16/23

№ 3 (-4- 25 - 50 ) : (-5 )- 20 +5 = -79 :( -5) -20 +5= 15, 8- 15=0,8

№ 4 - 4 + 400 : ( 28 2 + 44) - 8= -4 + 400 : 326 -8= - 12 +200/163=-12 + 1 37/163 = -11 163/163 + 1 37/163= -10 126/163

№ 5 -32 + 8 • ( 42 : (-2) - 22 )-20= - 32 + 8 *( -43) -20=-32 - 344 -20= - 396

№ 6 (-33 - 34 : 2) 10-100=( -33 -17) *10 -100= - 500 -100= -600

№ 7 ( 45 - 3- 5) : (-3) - 5 +25 = 37 : (-3) -5 +25= - 12 1/3+20 = 19 3/3 - 12 1/3= 7 2/3

№ 8 - 15 + 250 : (15 5 - 50) - 8 : 3 = -15 + 250: 105 -8:3= -15 + 50/21 - 8 :3 = -15 + 2 8/21 -2 2/3= -15 + 2 8/21 - 2 14/21= -15 -6/21= - 15 6/21= - 15 2/7

№9 (-46 - 4 ) 2 - 15 : 3+200= - 50*2 - 5+200= -100 -5 +200 = 200 -105= 95

№ 10 - 48 : 16 + 2 (55 - 15) - 125= -3 + 2*40= - 3 +80 = 77
