# Read the input matrix elements
a, b = map(int, input().split())
c, d = map(int, input().split())

# Calculate M squared elements
e = a * a + b * c
f = a * b + b * d
g = c * a + d * c
h = c * b + d * d

# Calculate M cubed elements
i = e * a + f * c
j = e * b + f * d
k = g * a + h * c
l = g * b + h * d

# Output the result
print(i, j)
