Change the response to multiply the two arguments and return their product

It keeps telling me that 25 is being returned when they pass in /multiply/2.5/5. I had to set num1 and num2 to default values of 5 for a previous task, but I'm not sure why those values aren't being overrided when the new values are being passed into the URL.

flask_app.py 
from flask import Flask

app = Flask(__name__)

@app.route('/multiply')
@app.route('/multiply/<int:num1>/<int:num2>')
@app.route('/multiply/<int:num1>/<float:num2>')
@app.route('/multiply/<float:num1>/<int:num2>')
@app.route('/multiply/<float:num1>/<float:num2>')
def multiply(num1=5, num2=5):
    multiply = 5*5
    return str(multiply)
    return "{} * {} = {}".format(num1, num2, num1*num2)
    return "{}".format(num1*num2)

You have multiple return statements and you're always returning the variable multiply first which is 5 * 5. You need to change this line to multiply the function variables and you can remove the other return statements.

multiply = num1 * num2
return str(multiply)
