-(- 125 + 63 + 57) – ( 10 – 83 – 37)
= 125 – 63 – 57 – 10 + 83 + 37
= (-63 + 83) + ( – 57 + 37) + ( 125 – 10)
= 20 + (-20) + 115
= 0 + 115
= 115
Giải đáp:
– ( – 125 + 63 + 57 ) – ( 10 – 83 – 37 ) = 115
Lời giải và giải thích chi tiết:
– ( – 125 + 63 + 57 ) – ( 10 – 83 – 37 )
= 125 – 63 – 57 – 10 + 83 + 37
= 115
