# 🟡 Devtoberfest 2026 - Week 2 - Equation Puzzle

<!-- description --> This is the equation puzzle for Week 2 of Devtoberfest.

## You will learn

- A lot about technology – and yourself – during Devtoberfest
- How to have fun

## Intro

>**PLEASE NOTE:** This tutorial will not be working until the start of Devtoberfest.

Here is an equation that you have to solve.

![Equation](https://raw.githubusercontent.com/sap-tutorials/developer-advocates/main/tutorials/devtoberfest2026-fun-week2-equation/equation.png) 

Here is the exact same equation written as a Python function.

```Python
import math

def calculate_expression(a, b, c, d, e, f, g, h, i, j):
    """
    Evaluates the nested expression:
    [ (((sqrt(a - b) / (c - d)) + e) / f) + g ] * (h / i)**2 - j
    """
    inner_fraction = math.sqrt(a - b) / (c - d)
    middle_term = (inner_fraction + e) / f
    outer_term = (middle_term + g) * (h / i) ** 2
    
    return outer_term - j   
```

Answer the following questions to get values for the 10 variables, plug them in, and enter the answer below.

* a = the year SAP was founded
* b = decimal ASCII code for the currency symbol for US dollar
* c = Get the clue from the Dubugging video in the [Expert sessions: CAP Node.js playlist](https://www.youtube.com/playlist?list=PL6RpkC85SLQDxW_6INTtprrvZ3WiXT8u5). Just listen to DJ. 
* d = Second name of SAP's ERP product for small and medium-sized enterprises, developed by a company founded by the father of former SAP CTO Shai Agassi
* e = transaction code (numeric part only) of ABAP Editor
* f = official technical version number for SAP NetWeaver 2004s 
* g = number of digits in all client codes
* h = number of hex digits in a standard GUID
* i = the sum of the digits in the year when SAP announced the Autonomous Enterprise, plus 6  
* j = Get clue from our [Devtoberfest promo video](https://www.youtube.com/watch?v=ZvxLbaMg2Gw). 

>The final answer has something to do with Devtoberfest and SAP TechEd.
