Question

calcula las operaciones combinadas:


A) 38 - ( 6+2 ) x 4 =

B) ( 25 - 5) ÷ 4 + (16 - 4) x 2 =

C) ( 9 - 5 ) x 4 + ( 16 - 4 ) ÷ 3 =

D) ( 19 - 7 - 5) x 6 - ( 20 - 12) x 3 =

Answer 1

A) 38-(6+2)x4
= 38-(8)x4
=30x4
=120
B) (25-5)/4 + (16-4)x2
=20/4 + 8x2
5+16
=21
C)(9-5)X4 + (16-4)/3
=4X4 + 12/3
=16+4
=20
D)(19-7-5)x6 -  (20-12)x3
=7x6 - 8x3
=42-24
=18

Answer 2

38 - ( 6+2 ) x 4 
38 - (6)4
38 - 24
14


( 25 - 5) ÷ 4 + (16 - 4) x 2 
(20):4 + (12)2
5 + 6
11


( 9 - 5 ) x 4 + ( 16 - 4 ) ÷ 3  
(4)4 + (12):3
16 +4
20


( 19 - 7 - 5) x 6 - ( 20 - 12) x 3 
(12-5)6 - (8)3
7(6) - 24
42 - 24
18
