Add routes to allow floats or a combination of floats and ints. Where have I gone wrong?

I'm confused..., I've run this in workspaces and I think I have read and compared all the other posts where people are having trouble and still cant get past the 4th task in the challenge. I've run this both with add/ and multiply/ and it works. what is the challenge asking for that I have not provided.

flask_app.py 
from flask import Flask

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

Okay.., first, thanks Mohammed. I did go look at that link there that you posted. looks like the moderator says that it works, which it does. I wound up taking a few hours away and just restarted the challenge. After I completed it I was confused because it appeared that I had missed some steps along the way..., and that's where my confusion came from.

I guess I had completed a couple of the tasks ahead and all I needed to do was just click through to the next part of the challenge. It was confusing for me, but after I sat and looked at what I had done and looked at the forums I saw that there were a few others having sorta the same issue one way or another.

I'll have to revisit this exercise again shortly.

Had the same issue returned a string instead seems to work

from flask import Flask

app = Flask(name) @app.route('/multiply') @app.route('/multiply/<int:num1>/<int:num2>') @app.route('/multiply/<float:num1>/<float:num2>') @app.route('/multiply/<int:num1>/<float:num2>') @app.route('/multiply/<float:num1>/<int:num2>')

def multiply(num1=5, num2=5): return str(num1 * num2)
