500 - 25 x 3 + 25
= 500 - ( 25 x 3 + 25 )
= 500 - ( 75 + 25)
= 500 - 100
= 400
~~~HỌC TỐT NHA~~~
500 - 25 × 3 + 25
= 500 - 75 + 25
= 425 + 25
= 450
Hok tốt nha
500-25×3+25
=500-25×3+25×1
=500-25×(3+1)
=500-25×4
=500-100
=400
500 - 25 x 3 + 25
= 500 - 75 + 25
= 425 + 25
= 450
500 - 25 x 3 + 25
= 500 - 75 - 25
