Example: Adding a Calculator to Our Agent › The Problem We're Solving

Remember this scenario from earlier? You ask your agent: "What's $1,234 \times 5,678$?"

Without tools, the agent approximates:

Let me work through this:
1,234 × 5,678 = approximately 7,010,000

So the answer is about 7,010,000.

The agent is guessing. The actual answer is $7,006,652$. That's an error of over $3,000$. Not acceptable if you're calculating costs, revenues, or anything that matters.

With a calculator tool, the agent will:

1. Recognize this is a math problem
2. Call the calculator with the expression
3. Return the exact answer: $7,006,652$

Let's build it.
