(17+2).3+5
(9-1). (4-1)
(12+2.5)-8
25-(15+6:3)
[40+2.(11-3)]
15+[4+(7.3+1)]-3
80-[22+(5.2-1)+6]

Answer 1

(17 + 2 ) . 3 + 5 =
19 . 3 + 5 =
57 + 5 = 
62
------------------------------------
(9-1) . (4-1) =
8 . 3 =
24
------------------------------------
(12 + 2.5 ) - 8 =
(12 + 10) - 8 =
22 - 8 =
14
------------------------------------
25 - (15 + 6:3) =
25 - (15 + 2) =
25 - 17 =
8
------------------------------------
[40 + 2 (11 -3)] =
[40 + 2 . 8 ]=
40 + 16 =
56
-------------------------------------
15 + [4 + (7.3 + 1)] - 3 =
15 + [4 + (21 + 1) ] - 3 =
15 + [4 + 22 ] - 3 =
 15 + 26 - 3 =
41 - 3 =
38
--------------------------------------
80 - [22 + (5.2 -1) + 6 ] =
80 - [22 + (10 - 1) + 6] =
80 - [22 + 9 + 6] =
80 - 37 =
43
