Solution code:
A,B=list(map(int,input().split()))
print(max(A+B,A-B,A*B))

Submission status: Accepted

Solution code:
A,B = map(int, input().split())

wa = A + B
sa = A - B
syou = A * B
Z = [wa, sa, syou]
print(max(Z))

Submission status: Accepted

Solution code:
a,b = map(int, input().split())
ans = a+b
if ans < a-b:
  ans = a-b
if ans < a*b:
  ans = a*b

print(ans)
