Пожалуйста помогите сделать 549 номер плиз

Answer 1

№1) (512 + 16) - 1 14 = -812
1) 512 + 16 = 512 + 212 = 712
2) 712 - 1 14 = 712 - 54 = 712 - 1512 = -812

№2) 4 23 + (-4 13 - 45) = 215
1) -4 13 - 45 = -133 - 45 = -6515 - 1215 = -7215
2) 4 23 + (-7215) = 143 - 7215 = 7015 - 7215 = 215

№3) (58 - 712) - (-58) = 1936
1) 58 - 712 = 2036 - 2136 = -136
2) -136 - (-58) = -136 + 58 = -136 + 2036 = 1936

№4) (3 15 - 2 23) + (-35) = -115
1) 3 15 - 2 23 = 165 - 83 = 4815 - 4015 = 815
2) 815 - 35 = 815 - 915 = -115
