Bardzo ważne prosze was napiszcie to dobrze dzieki ;)

Answer 1

7-3+4 =8

15-17+19-21+23-25+27-29=?

118-287-108-287=?

(120-2)×287-(100+8)×287=118x287=33866-108x287=30996

17×16-3×16=16×(17-3)=?

Answer 2

7-3+4=4+4=8

15-17+19-21+23-25+27-29=-8

118-287-108-287=-564

(120-2)*287 -(100+8)*287= 118*287-108*287=33866-30996=2870

17*16-3*16=16*(17-3)=16*14=224

Answer 3

7-3+4=8

15-17+19-21+23-25+27-29= - 8

118-287-108-287= - 564

(120-3)*287-(100+8)*287=9606177

17*16-3*16=16*(17-3)=224

Myslę ze pomogłem pzdr :D
