In membrul stang puneti paranteze (rotunde/patrate/acolade) astfel incat egalitatile sa fie corecte: c)7+5×3+2-2×4-1=26
d)3×6-2×3-1+8=14
e)3×9-2×7-5=17
g)12×6-2+15:5-2=53
h)2×3×4+12:3-1=16
i)41-5×9-4+4:9-5=17
Va rog ajutati-ma, e pentru maine!!

c) 7+5*3+2-2*4-1=26  =>  {[7+(5*(3+2))]-2*(4-1)}=26  =>  [7+(5*5)]-2*3=26  =>
   (7+25)-6=26  =>  32-6=26

d) 3*6-2*3-1+8=14  =>  {[3*(6-(2*(3-1)))]+8}=14  =>  [3*(6-(2*2))]+8=14  => 
    (3*(6-4))+8=14  => (3*2)+8=14  => 6+8=14

g)  12*6-2+15:5-2=53  =>  {[12*(6-2)]+15:(5-2)}=53  => (12*4)+15:3=53  =>      48+5 =53
