F 120:5=24
G )96:8:2=6
H) 36-36:18=36-2=34

4) a) 23+7•{41+4•[3+8•(132-80)-59]}+1002=
23+7•[41+4•(3+8•52-59)]+1002=
23+7•[41+4•(3+416-59)]+1002=
23+7•(41+4•360)+1002=
23+7•(41+1440)+1002=
23+7•1481+1002=23+10367+1002=11392

B) (406-116)+132+8•{125-5•[340-2•(418-253)]}
290+132+8•[125-5•(340-2•165)]
422+8•[125-5•(340-330)]
422+8•(125-5•10)=422+8•75=422+600=1022

C) 1+11•{1+11•[1+11•(121-120)]}+121
1+11•[1+11•(1+11•1)]+121
1+11•(1+11•12)+121
1+11•133+121=1+1463+121=1585

D) [103-3•(231-207)]•[3+5•(2+3•35)]
(103-3•24)•(3+5•107)
(103-72)•(3+535)
31•538=16678
