Variables & Formulas

Name your numbers, build connected expressions, and explore what-if scenarios.

Variables are just names

Give any number a name with =:

price = 100
tax_rate = 8.5%
tax = price * tax_rate
total = price + tax

Change price and everything downstream updates instantly.

Formulas reference earlier rows

Every variable you define is available in later rows. Build complex calculations step by step:

monthly_income = 5000
rent = 1500
food = 600
transport = 200
savings = monthly_income - rent - food - transport
savings_rate = savings / monthly_income  // as a percentage
