# Convert from celsius to farenheit
# (9//5)*C + 32
# get Celsius temperature c

reply = input( 'Enter Celsius temperature: ' )

c = int( reply )

# compute respectively, f1 and f2, the decimal and integer Fahrenheit equivalents of c 

f1 = ( 9//5 ) * c + 32
# f2 is the clearest form for our equation
f2 = ( ( 9 * c ) // 5 ) + 32

# PEMDAS - python has "operator precedence"
# it computes multiplication and division before addition and subtraction
# reads left to right within the same type
f1 = 9 * c // 5 + 32
f1 = 32 + 9 * c // 5

# display results

print( c, 'C =', f1, 'F' )
