# compute respectively, f1 and f2, the decimal and integer Fahrenheit equivalents of c
f1 = ( 9/5 * c ) + 32 # decimal temperature
# python follows PEMDAS, generally - operator precedence
# multiplication and division are done in one step from left to right
f2 = ( 9 * c ) // 5 + 32 # int(f1) would work, but decimal arithmetic is less precise than integer arithmetic

#  9//5 * c + 32 this doesn't work, because 9//5 = 1
# if your output doesn't look correct, look at order of operations and integer division
# arithmetic style guidelines - add spaces separating multiplication/division from addition/subtraction
