Ask a big question in one go and the AI jumps straight to a conclusion. For a polite email, that's fine. For pricing, costs or a choice between two options, ask it to work in steps.
The mistake most people make
People put the problem, the sums and the decision into one long paragraph. The AI tries to answer everything at once and gives shallow advice.
“We run a coaching institute in Jaipur with 120 students paying ₹3,500 monthly. Our rent is ₹85,000, teacher salaries are ₹1,80,000, and electricity is ₹15,000. Should we open a second branch in Kota or expand online, and what will our margin be next year?”
“You should open a branch in Kota because it is a renowned education hub. Your current revenue is ₹4,20,000 and total costs are ₹2,80,000, giving a healthy profit of ₹1,40,000. With Kota, your margins will double within 12 months.”
How it works: the Class 10 board exam
Remember your Class 10 maths board exam. The question asks for the volume of a cone on top of a hemisphere. Write only 'Volume = 432 cubic cm' and the examiner gives you nothing. Try it all in your head and you'll probably slip. Write Step 1 (radius = 6 cm), Step 2 (volume of the hemisphere), Step 3 (volume of the cone), and each step holds up the next. AI is similar. It writes one word at a time, and everything it has already written shapes what comes next. When it writes Step 1 on the page, Step 2 is built on it.
Three ways to get better reasoning
1. Ask for the steps
Tell the AI the order to work in: 'Work out the fixed costs first, then the cost per student, then compare the two options.'
2. Split the job into separate requests
First request: sort the costs. Second request: list the risks. Third request: compare the two options against those risks.
3. Test the weak spots
Ask: 'Which step in this plan fails if a quarter of our students leave during the summer holidays?'
Habits for step-by-step work
I need to make a business decision. Here is the situation and my figures: """ [Paste your situation and the figures from your own records here] """ Don't give me a recommendation straight away. Work through these steps in order: Step 1: Set out the money side using only my figures: fixed costs, what each sale or customer brings in after its own costs, and cash in hand. Show each sum. Step 2: Name the 3 biggest limits on what I can do. Step 3: Compare Option A and Option B on money needed, effort to run, and time to cover the cost. Step 4: Say which option looks stronger and the main risk that could make it fail. Rules: - Use only the figures I gave. Don't invent a figure, rate, tax or cost. Where one is missing, write [CHECK: what is missing]. - Don't state any tax, legal or loan rule. Mark it [CHECK] instead. End with this line: "Have your CA check these figures before you commit any money."
The steps stop the AI jumping to an answer, and the rules stop it filling gaps with made-up numbers. The final check stays with you and your CA.
Why does asking the AI to work step by step help it reason better?
Show the answer
The AI writes one word at a time, and what it has written shapes what comes next. A written step gives the next step something to build on, and it lets you check each step yourself.
