Practical Example

Let’s solve a real example to understand how the calculator works.

Example Expression:

(10 + 5) * 3^2 - 6 / 2

Step-by-Step Breakdown:

1. Solve inside parentheses:
   10 + 5 = 15
2. Calculate exponent:
   3² = 9
3. Multiply:
   15 × 9 = 135
4. Divide:
   6 ÷ 2 = 3
5. Subtract:
   135 − 3 = 132

Final Result:

132

Instead of solving manually, the calculator delivers the result instantly.
