Everything you need to calculate
Powerful features for individuals and teams who take their math seriously.
Operator Isolation
Each operator runs in its own containerized microservice. Addition never touches subtraction. Mathematically sandboxed.
Digit-Level Encryption
Every digit encrypted individually. Your "7" is as secure as your "3". NSA-grade number protection.
PEMDAS Compliance Engine
Order of operations guaranteed. Parentheses processed first, every time. Audited quarterly.
Decimal Point as a Service
Our proprietary DPaaS ensures your decimal lands exactly where it should. Sub-pixel precision.
Division by Zero Protection
Enterprise-grade zero handling. Real-time detection. Automatic failover to infinity.
Carry-the-One Automation
AI-powered carrying algorithm. Never manually carry again. 99.97% carry accuracy.
How it works
Get started in three simple steps
Enter your numbers
Use our intuitive keypad to input any number from 0-9. Full precision on Pro. Limited decimals on Plus/Team.
Choose an operator
Select from +, -, ×, or ÷. All four operators included on every plan.
