# 30 is divided by 6 and then the result is added to 25
print "Hens", 25 + 30 / 6

# Calculates and prints the number of Roosters
# Calculation of 100 - 25 * 3 % 4 is permormed as following:
# 1) 25 * 3 = 75
# 2) 75 % 4 = 3 (3 is the remainder of 75 divided by 4)
# 3) 100 - 3 = 97

print "Now I will count the eggs:"

# Calculates the number of eggs and prints this number on the screen
# Calculation of 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6 is performed as following:
# 1) 4 % 2 = 0
# 2) 1 / 4 = 0.25 (but it will only use integer part, i.e. 0)
# 3) 3 + 2 + 1 - 5 + 0 - 0 + 6 = 1 + 6 = 7
