Implement a function that performs basic arithmetic operations (addition, subtraction, multiplication, and division) on two numbers. The function should take two numbers and an operation string as input and return the result of the operation.
Examples:
Input: num1 = 10, num2 = 5, operation = '+'
Output: 15
Explanation: Addition: 10 + 5 = 15
Input: num1 = 10, num2 = 5, operation = '*'
Output: 50
Explanation: Multiplication: 10 * 5 = 50
