a)
40-(9+8)+109=40-17+109=27+109=136
(66+147)+10=213+10=223

b)
9x6+(831-80)=54+751=755
7x6+9+32=42+41+83

a) 5*8-(9*0+64:8)+109=

=40-(0+8)+109

=40-8+109

32+109=141

(6*11+147)+50:5=

=(66+147)+10

=213+10=223

b) 81:9*6+(831-8*10)=

=9*6+(831-80)

=54+751

=805

(77-69)*6+45:5+4*8=

=8*6+9+32

=48+9+32

=89
