2. 45+36:4:3X5-9=
3. 100-8X6+16:2=
4. (4X9-28)+(42:6X8)=
5. 100-(32+8X6-59):3=

Va rog ajutati-ma!dau coroana!

Answer 1

Răspuns:

1. 8X3:6X3:6X10:4=5

2. 45+36:4:3X5-9=45+15-9=51

3. 100-8X6+16:2=100-48+8=60

4. (4X9-28)+(42:6X8)=(36-28)+(7·8)=8+56=64

5. 100-(32+8X6-59):3=100-(32+48-59):3=100-21:3=100-7=93

Answer 2

Răspuns:

Explicație:

8×3:6×3:6 ×10: 4 =

24 : 6×3 :6 × 10 : 4 =

4 × 3 : 6 × 10 : 4 =

12 : 6 × 10 : 4 =

2 × 10 : 4 =

20 : 4 =

5

45 + 36 : 4 : 3 × 5 - 9 =

45 + 9 : 3 × 5 - 9 =

45 + 3 × 5 - 9 =

45 + 15 - 9 =

60 - 9 =

51

100 - 8 × 6 + 16 : 2 =

100 - 48 + 8 =

52 + 8 =

60

(4×9 - 28 ) + ( 42 : 6 × 8 ) =

(36 - 28 ) + ( 7 × 8 ) =

8 + 56 =

64

100 - ( 32 + 8 × 6 - 59 ) : 3 =

100 - ( 32 + 48 - 59 ) : 3 =

100 - ( 80 - 59 ) : 3 =

100 - 21 : 3 =

100 - 7 =

93
