THREE SIMPLE STEPS

How to use the scientific calculator

01

Type the expression

Use your keyboard or the keys, e.g. 2×(3+4)^2 or sin(30)+log(100). The result shows as you type.

02

Press =

Press = or Enter. The answer stays on screen; type an operator to keep going from it, or a number to start again.

03

Reuse results

Click a line in the history to edit it, use Ans for the last answer, or keep a value in memory with M+.

Worked examples

Compound interest

How much does $1,000 grow to at 5% a year, compounded monthly, over 10 years?

  1. Type 1000×(1+0.05÷12)^(12×10).
  2. Brackets are worked out first, then the power, then the multiplication.

= 1,647.00949769028 – about $1,647.01.

A right triangle

The two short sides are 3 and 4. How long is the long side?

  1. Type √(3^2+4^2).
  2. 3² + 4² = 25 and √25 = 5.

= 5

Lottery odds

How many ways are there to pick 6 numbers out of 49?

  1. Type nCr(49,6).
  2. That is 49! ÷ (6! × 43!).

= 13,983,816 – a 1 in 13,983,816 chance.

Order of operations

( ) → x², x³, !, % → ^ → − (sign) → × ÷ mod → + −2^3^2 = 2^9 = 512 −2^2 = −4 200 + 10% = 220

Brackets come first, then powers (worked from right to left), then multiplication and division, then addition and subtraction. A number next to a bracket, a constant or a function is multiplied: 2π, 3(4+1).

Answers are shown to 15 significant digits, so 0.1 + 0.2 shows 0.3 rather than a long tail of rounding digits.

Scientific Calculator FAQ

Can I type with my keyboard?

Yes. Type the expression as you would write it: digits, + − * / ^ ( ), ! for factorial, % for percent and function names such as sin, cos, log or sqrt. Enter gives the answer, Esc clears.

How do I switch between degrees and radians?

Use the Deg / Rad switch above the expression. It changes how sin, cos and tan read their angle and how their inverses give it back. In degrees, sin(30) = 0.5 and tan(90) is undefined.

Why does 0.1 + 0.2 show 0.3?

Computers store most decimals as binary fractions, which adds tiny errors. The calculator rounds every answer to 15 significant digits, which removes them without hiding real precision.

How does the percent key work?

50% is 0.5. Added to or taken from a number, it means a share of that number: 200 + 10% = 220 and 200 − 25% = 150, like a desk calculator.

What functions are available?

sin, cos, tan and their inverses, sinh and cosh, ln, log (and log(x, b) for any base), eˣ, 10ˣ, square, cube, powers, square, cube and n-th roots, factorial (including decimals), nCr, nPr, mod and absolute value, plus π, e and Ans.

Is my history saved?

The last 50 calculations, the memory and the angle setting are kept in your browser so they are there next time. Clear removes the history.

Is it free?

Yes. No sign-up, no limits, and it works in your browser.
