4x8+(1700+2490-680)x0 = 4x8 + 0 =32
(81:9)+(7x8-6x9)-(3001-2928) = 9+(56-54)-73=9+2-73=18-73= -55
(2640-1980+1067)x2x 0 x5 = 0
(36:4+25:5)+7x2x8x9 = 9+5 +14x8x9=14+112x9=14+1008=1022

25x100-4x100+3x19 = 2500-400+57=2100+57=2157
(80:10)+(1927-1900):3+2 = 8+27:3+2=8+9+2=19
(765-235+70):10+16x9 = (530+70):10+144=600:10+144=60+144=204
6x124+6x76-12x1x0=744+456-0=1200
