How to do mathematical operations in this app? I am not able to get output if write a code >>>2+3 and pressing run command..

Answer 1

in python you just do like that
t = input("Enter a num:")
a = input("Enter a num:")
print(int(t) + int(a))
or
print (2+3)

Answer 2

I see you are learning Python.

If you're in the Python console (e.g. using IDLE on a PC where the prompt is '>>>'), all you have to do is hit 'enter', so
>>>2+3
5
>>>

If you're in the Code Playground, then do what @Gawen said, e.g.
type:

print(2 + 3)

press 'run'

you should get:

5

Make sure you aren't typing '>>>' as part of the code :)

If you do, you will get:

File "..\Playground\", line 1
>>>print(2+3)
^
SyntaxError: invalid syntax
