Answer 1

a) 120:4+160:8+(101+99):100=
=30+20+200:100
=50+2
=52
b) (63+56)x4-(101+11):2=
=119x4-112:2
= 476-56
=420
c) 1000-(125+75)x3-(25+75)x4=
=1000-200x3-100x4
=1000-600-400
=400-400
=0
d) 23x(157-144)-159-(22+110)=
=23x13-159-132
=299-159-132
=140-132
=8
e) 135+5000:1000+3x(40+4)
=135+5+3x44
=140+132
=272
f) 36+0+99-11+11=
=135
g) 909-909x(102-101±0)-99x(9-9)
=909-909x1-0
=909-909-0
=0
h)3x(6-3)+61+(20+0):5=
=3x3+61+20:5
=9+61+4
=74
i)138+(9-1)x2:8-2x(100-13)x2=
=138+8x2:8-2x87x2
=138+2-194x2
=140-388
=-248
j) 7+1x(7-1)x7:7=
=7+1x6x7:7
=7+42:7
=7+6
=13
