| AC (All Clear) |
Press the AC button to clear all inputs and reset the calculator to its initial state.
Example: If you've made a mistake while calculating, simply press AC to start over. |
| Basic Calculation (+, -, ×, ÷) |
You can perform basic arithmetic operations.
Steps: 1. Press 6 → 2. Press + → 3. Press 3 → 4. Press = → Output: 9 Explanation: This works just like any other basic calculator. You can use it for addition, subtraction, multiplication, and division. |
| Square Root (√) |
The square root function is used to find the square root of any positive number.
Steps: 1. Press √ → 2. Press 49 → 3. Press = → Output: 7 Explanation: This will return the square root of 49, which is 7. Square roots only work with non-negative numbers. |
| Square (x²) |
This button squares the number you enter.
Steps: 1. Press 5 → 2. Press x² → Output: 25 Explanation: The number 5 is squared, resulting in 25. |
| Percentage (%) |
The percentage function helps convert a number into a percentage value.
Steps: 1. Press 150 → 2. Press % → Output: 1.5 Explanation: The calculator divides 150 by 100 to convert it to a percentage value. |
| Sign Change (±) |
The sign change function allows you to toggle between positive and negative numbers.
Steps: 1. Press ± → 2. Press 9 → Output: -9 Explanation: This changes the sign of the number, turning it from positive to negative. |
| Trigonometric Functions (sin, cos, tan) |
These buttons allow you to calculate the trigonometric values of angles.
Steps: 1. Press sin → 2. Press 30 → 3. Press = → Output: 0.5 Explanation: This will give the sine of 30 degrees (make sure you are in DEG mode, not RAD). |
| Logarithm (log) |
The logarithm function is used to calculate the logarithm of a number with base 10.
Steps: 1. Press log → 2. Press 1000 → 3. Press = → Output: 3 Explanation: The logarithm of 1000 with base 10 is 3 (log₁₀ 1000 = 3). |
| Exponential (EXP) |
The exponential function calculates powers of 10 (10 raised to the power of the input number).
Steps: 1. Press 3.5 → 2. Press EXP → 3. Press 4 → Output: 35000 Explanation: This is the same as 3.5 × 10⁴, or 35000. |
| Factorial (x!) |
The factorial function is used to calculate the product of all integers from 1 to the input number.
Steps: 1. Press 5 → 2. Press x! → Output: 120 Explanation: This is the product of 5 × 4 × 3 × 2 × 1, which equals 120. |
Now that you have a complete understanding of each function, try using these steps directly on the calculator above. With this, you can easily perform both simple and advanced calculations.
Common Mathematical Formulas for Easy Calculation
Discover some essential formulas that you can easily calculate using our online scientific calculator. Whether you're solving algebraic expressions, trigonometric problems, or physics equations, these formulas will help you get accurate results quickly.
Algebra Formulas
- Quadratic Formula: x = (-b ± √(b² - 4ac))/2a
- Binomial Expansion: (a + b)² = a² + 2ab + b²
- Difference of Squares: a² - b² = (a + b)(a - b)
Trigonometric Formulas
- Pythagorean Identity: sin²θ + cos²θ = 1
- Double Angle: sin(2θ) = 2sinθcosθ
- Law of Sines: a/sinA = b/sinB = c/sinC
Calculus Formulas
- Power Rule: d/dx(x^n) = n·x^(n-1)
- e Rule: d/dx(e^x) = e^x
- ln Rule: d/dx(ln x) = 1/x
Physics Formulas
- Einstein's Energy: E = mc²
- Force: F = ma

How to Use Scientific Notation on a Calculator
Scientific notation allows us to express extremely large or very small numbers in a more compact and manageable format. If you're using a calculator, here's how you can enter numbers in scientific notation:
- Begin with the coefficient — a number between 1 and 10.
- Press the EXP button (or EE on some models).
- Enter the exponent that represents the power of 10.
- To enter a negative exponent (for very small numbers), use the ± key after pressing EXP.
Example: Here's how to input 3.5 × 10-4 on your calculator:
- Enter 3.5
- Press EXP
- Tap ± to make the exponent negative
- Type 4 as the exponent
Your calculator should display 3.5e-4, which is the same as 0.00035 in standard notation.
TI-84 Plus Tip: To input 3.5 × 10-4 on a TI-84 Plus:
- Press 3, then the . key, followed by 5 to input 3.5
- Hit the 2nd key, then EE (this is the EXP function)
- Use the (–) button for a negative exponent
- Enter 4 to complete the exponent
The screen will show 3.5e-4, representing 0.00035 in regular form.
