Every expression have to be solved in step by step . Do not write the answers only. Here A=10, B =15, C =5 and D =20. All variables are integers.

1. A = A * B + D / C + + + C - - - D
2. B += A & B | C * A * D / B && C
3. C *= A | B || C && D & A
4. A = A + B * C / D % C +++ B +++A * B
5. D = A + B == C >= D && B
