There seems to be a syntax error in the "

`elif choice == "%":`

" statement. Please help me out.

**What I have tried:**
1 def add(a, b):
2 return a + b
3
4
5 def subtract(a, b):
6 return a - b
7
8
9 def multiply(a, b):
10 return a * b
11
12
13 def divide(a, b):
14 return a / b
15
16
17 def power(a, b):
18 return a ^ b
19
20
21 def remainder(a, b):
22 return a % b
23
