A = 7 - 7 x 56 x 2 - 5
A = 7 - 35
12 - 5
A = - 28/7
A = 7 x - 4 / 7 x 1
A = - 4
B = 1/3 + 14/3 : 35/12
B = 1/3 + 14/3 x 12/35
B = 1/3 + 168/105
B = 1 x 35 / 3 x 35 + 168/105
B = 35/105 + 168/105
B = 203/105
B = 7 x 29 / 7 x 15
B = 29/15
C = 4/5 x 5/6 x 6/7
C = 20/30 x 6/7
C = 120/210
C = 30 x 4 / 30 x 7
C = 4/7
D = - 25/21 : - 5/7
D = - 25/21 x - 7/5
D = 175/105
D = 35 x 5 / 35 x 3
D = 5/3
