Question

[(23x34:2-15x17):8+17x5]:2-13x3=
[(26+5x[42:7+5x(30+6x15:3=
7x(37x8+126:3)-[3000-5x(48:8+810:9)]:10=
[15x15+(5x20x6-15x25)]:10:9:5=
123-5x[(810:10:9+240:10:6)+25:5x2]=
6+4x[20+3x(4+8x3)-54]-103x2=

Answer 1

[(391-255)÷8+85]÷2-39=
[136÷8+85]÷2-39=
102÷2-38=51-38=13

[(26+5×...mai scrie l inca o data ca nu stiu cum sunt puse parantezele
7×(296+42)-[3000-5×(6+90)]÷10=7×338-[3000-5×96]÷10=2366-2520÷10=2366-252=2114
[225+(600-375)]÷10÷9÷5=[225+225]÷10÷9÷5=450÷10÷9÷5=45÷9÷5=5÷5=1
123-5×[(9+4)+10]=123-5×23=123-115=8
6+4×[20+3×(4+24)-54]-206=6+4×[20+3×28-54]-206=6+4×[20+84-54]-206=6+4×50-206=6+200-206=0
merit coroana pt atatea calcule...sunt bine facute
