Question

calculeaza respectand ordinea operatiilor :
5x100+80x10-400:10=

(540:6+450:9)-760:10=

800:100+(850-960:3)=

Answer 1

5 x 100 + 80 x 10 - 400 : 10 = 540
= 500 + 80 - 40 = 
= 580 - 40 =
= 540 

( 540 : 6 + 450 : 9 ) - 760 : 10 =64  
= ( 90 + 50 ) - 76 = 
= 140 - 76 =
= 64 


800 : 100 + ( 850 - 960 : 3 ) = 538 
= 8 + ( 850 - 320 ) = 
= 8 + 530 =
= 538 

Answer 2

5 × 100 + 80 × 10 - 400 : 10 =
500 + 800 - 40 =
1300 - 40 =
1260


( 540 : 6 + 450 : 9 ) - 760 : 10 =
( 90 + 50 ) - 76 =
140 - 76 =
64


800 : 100 + ( 850 - 960 : 3 ) =
8 + ( 850 - 320 ) =
8 + 530 =
538
