A calculator can be inserted anywhere inside a form and **supports straightforward operations for pretty much any purpose** from counting inputs to scoring a test, for instance.

### Add

### Subtract

### Multiply

### Divide

### Equal

Forms and surveys can handle as many calculations as you need, anywhere you need them. In fact, you can **set up one calculator to use the outcome of another.**

Now here’s the magic part... **The calculator can also handle calculations within calculations.** Like formulas. Handy for calculating a shopping cart’s subtotal and VAT in a single calculator.

Imagine your powers when you put Tripetto’s mind to it ;)

It almost goes without saying that you can **select any respondent input for calculations.** Actually, you may include as many inputs as you like in a single calculation.

Beyond operations like adding, subtracting, multiplying and dividing, the calculator also supports advanced operations for **more mathematically challenging use cases.**

### Roots

### Powers

### Functions

### Constants

### More

**Mindblowing things happen when logic and calculators come together.**

Funnel respondents into any desired flow based on age, score, probability, height, BMI etc. or any combination of factors. The possibilities are endless.
