How to Use the Simple Calculator

  1. Tap buttons or type. Example: 2+3*4, (2+3)*4, 50%.
  2. Press = or Enter to evaluate.
  3. Use Ans to reuse the last answer, e.g. Ans+10.
  4. Press AC or Esc to clear, DEL or Backspace to delete.
  5. Click Copy Result to copy the current answer or tap history to reuse.

Understanding Basic Calculation

A simple calculator respects operator precedence: multiplication and division before addition and subtraction, with parentheses overriding. Percent is postfix and converts to division by 100, so it composes with multiplication.

Precedence and parentheses

2+3*4 is 14 because * binds tighter than +. (2+3)*4 is 20 because parentheses force the addition first. Nesting like ((1+2)*3)/2 is allowed to any depth.

Percent

50% is 0.5. 200*10% is 20. This matches the Percentage Calculator for X% of Y, but here it is inline so 200*(10/100) is the same.

Ans and chaining

After 10+5=15, Ans holds 15. Typing Ans*2 gives 30. This lets you chain without retyping long numbers.

Honest limitations

Evaluation uses double precision. Overflow beyond 1e308 shows an error, and divide by zero shows Overflow instead of Infinity. For scientific functions like sin or log use the Scientific Calculator.

Privacy and Client-Side Security

Privacy Guarantee: All calculations occur locally inside your browser. Your expressions are never transmitted, stored, or recorded on remote servers.

Many calculators send every keystroke to a server. TinyToolzz keeps everything in-page: parsing and evaluation run with plain JavaScript in the tab.

Because nothing is uploaded, there is no waiting, no account, and no copy of your expressions retained anywhere. They exist only in the tab's memory and are cleared with AC or by closing the page.

Frequently Asked Questions

What operations are supported?
Addition +, subtraction -, multiplication *, division /, parentheses, percent % and Ans. Example 2+3*4=14, (2+3)*4=20, 50% =0.5, 200*10% =20.
Can I use the keyboard?
Yes. Type numbers and + - * / ( ) . % directly, Enter for =, Escape for AC, Backspace to delete. You can paste expressions like (100-20)*1.5.
What is Ans?
Ans holds the last result. After 5+5=10, typing Ans*2 gives 20. It updates after every successful evaluation.
How is percent handled?
Percent is postfix: 50% becomes 0.5. So 200*10% =20 and 100+10% is invalid - use 100*10% for 10. Use the Percentage Calculator for X% of Y directly.
Is my calculation sent to a server?
No. All evaluation runs locally in your browser with JavaScript. Your expressions are never transmitted, stored or logged anywhere. Closing the tab or clicking AC removes them from memory immediately.
What about divide by zero?
Division by zero shows an error. For example 5/0 gives Overflow error instead of Infinity.
