= (45 - 25) + (32 - 12) + 8
= 20 + 20 +8
= 48
45 + 32 +8 - 12 - 15 = ( 45-25) +( 32+8)-12
= 20 + 40 -12
= 60 - 12
= 58
45 + 32 + 8 -12 -25
= ( 45-25) + (32+8) - 12
= 20+40 - 12
= 60-12
=48
Sửa lại nha :)
\(45+32+8-12-25\)
\(=\left(45-25\right)+\left(32+8\right)-12\)
\(=20+40-12\)
\(=60-12\)
\(=48\)
45 + 32 + 8 - 12 - 25
= (45 - 25) + (8 + 32) - 12
= 20 + 40 - 12
= 60 - 12
= 48
45+32+8-12-25
=(45-25)+(8+32)-12
=20+40-12
=60-12
=48
