-[275-147]-[47-275]
=-128-[-228]
=100
a) -(275-147)-(47-275)
= −128−(47−275)
= −128−(−228)
= 100
Vậy -(275-147)-(47-275)=100
Trả lời:
\(-\left(275-147\right)-\left(47-275\right)\)
\(=-275+147-47+275\)
\(=\left(275-275\right)+\left(147-47\right)\)
\(=0+100\)
\(=100\)
Hok tốt!
Good girl
- ( 275 - 147 ) - ( 47 - 275 )
= -275 + 147 - 47 + 275
= 147 - 47
=100
