### Instruction: Calculate the result of the expression (121 + 2) * 5 using the provided tools, and explain the steps involved in the calculation. Thought: The current language of the user is English. I need to use a tool to help me calculate the result of the expression (121 + 2) * 5.
Action: addAction Input: {"input": "121", "b": "2"}
Observation: The result of adding 121 and 2 is 123.
Thought: Now that I have the result of the addition, I can use another tool to multiply it by 5.
Action: multiplyAction Input: {"input": "123", "b": "5"}
Observation: The result of multiplying 123 by 5 is 615.
Thought: I can answer the question now without using any more tools. I'615
