What It Calculates

Real Math. Natural Language. Not a Toy Calculator.

Type any math expression directly into the Quick Launch Toolbar. The calculator detects it automatically and shows the result instantly.

  • Basic arithmetic → 12+34*2 = 80 (respects order of operations)
  • Percentages → 15% of 250 = 37.5
  • Percentage markup → 20% more than 500 = 600
  • Percentage discount → 20% off 450 = 360
  • Tax calculations → 85 with 10% tax = 93.5
  • Tip calculations → tip on 65 = 9.75 (defaults to 15%)
  • Fractions → 1/4 of 200 = 50
  • Bill splitting → split 240 by 4 = 60
  • Averages → average of 80, 90, 70 = 80
  • Totals → sum of 150, 200, 75 = 425

Every result also shows the number written in words. 30 displays with “Thirty” underneath.

The Browser Calculator is one of 30+ tools in the Quick Launch Toolbar.

Talk to It Like a Human

Type What You Mean. Skip the Symbols.

Most calculators make you think in symbols. Browser Calculator understands plain English.

  • “15% of 200” → not 200 * 0.15
  • “20% off 500” → not 500 – (500 * 0.20)
  • “half of 300” → not 300 / 2
  • “85 with 10% tax” → not 85 * 1.10
  • “20% more than 1000” → not 1000 * 1.20
  • “discount 500 by 25%” → not 500 * 0.75
  • “triple 450” → not 450 * 3
  • “45 divided by 7” → not 45 / 7

You can even prefix with “what is” or “calculate.” Type “what’s 15% of 375” and it works.

Accurate Order of Operations

12 + 34 * 2 = 80. Not 92.

Browser Calculator respects mathematical precedence. Multiplication and division before addition and subtraction. Parentheses evaluated first.

12 + 34 * 2 → 12 + (34 * 2) → 12 + 68 = 80

It handles real math. Parentheses, nested expressions, decimals, negatives. Not a simple left-to-right calculator.

Built for Daily Use

Every Calculation You Actually Do.

  • Financial planning → “15% of 250000” = 37,500. Done. No extra tabs.
  • Quick discounts → “20% off 2400” = 1,920. Already on your clipboard.
  • Bill splitting → “split 186 by 4” = 46.5. No mental math.
  • Tax calculations → “85 with 10% tax” = 93.5.
  • Tip calculations → “20% tip on 65” = 13. Or just “tip on 65” for default 15%.
  • SEO metrics → “45/2000*100” = 2.25% CTR.
  • Content averages → “average of 80, 120, 95” = 98.33 shares.
  • Margin analysis → “(150-75)/150*100” = 50% margin.

Ctrl+Shift+Space. Type math. Get answer. Press Enter to copy. The calculator that comes to you.
