5) 25 - (3-2) + (4 - 1) =​

Answer 1

Respuesta:

1) ( 3 + 9 ) - 2 x 3 =

12 - 6 =

= 6

2) 16 + ( 13 - 22 ) =

16 + ( - 9 )

16 - 9

= 7

3) 4 x 23 - 3 x 3 + 5 x ( 4 + 3 )

92 - 9 + 20 + 15

83 + 20 + 15

= 118

4) 4 x ( 3 + 2 x ( 4 + 2 ) + 4 )

4 x ( 3 + 8 + 4 + 4 )

12 + 32 + 16 + 16

= 76

5) 25 - ( 3 - 2 ) + ( 4 - 1 )

25 - 3 + 2 + 4 - 1

22 + 2 + 4 - 1

24 + 4 - 1

28 - 1

= 27
