Basic Arithmetic Operations

Using the eLearnSmart web 2.0 scientific calculator is easy. Start with the basics. Our calculator makes simple math fast and clear. You can easily add, subtract, multiply, and divide.

To do these basic calculations:

Input Numbers: Click the number buttons on the calculator. For example, to enter “123”, press ‘1’, then ‘2’, then ‘3’.
Select Operation: After the first number, choose an operator. Press ‘+’, ‘-‘, ‘*’, or ‘/’.
Enter Second Number: Type the next number in your calculation.
Get Result: Press the ‘=’ button. The answer will appear on the screen.

For example, to calculate 25 + 15:

Type 25.
Press +.
Type 15.
Press =. The display will show 40.

This simple process gives you fast and accurate answers. Our web 2.0 calc is designed to be easy to use, making hard problems simpler to solve.

Advanced Functions (Trigonometry, Logarithms, Exponents)

Beyond basic math, the eLearnSmart web 2.0 scientific calculator is great for advanced problems. It offers a full set of functions for students and professionals. These include trigonometry, logarithms, and exponents, which are key for STEM subjects.

Here’s how to use the advanced functions:

Trigonometric Functions (sin, cos, tan):
- First, enter your angle. Check if the mode is ‘DEG’ for degrees or ‘RAD’ for radians. You can usually switch modes with a button like ‘DRG’.
- Then, press the function button you need (like ‘sin’, ‘cos’, or ‘tan’). The answer will appear right away.
- To use inverse functions (arcsin, arccos, arctan), you often need to press ‘2nd’ or ‘Shift’ first. These are used to find angles.
Logarithms (log, ln):
- Enter the number you want to find the logarithm for.
- Press ‘log’ for the base-10 logarithm or ‘ln’ for the natural logarithm (base e).
- Logarithms are important in many areas of science ^[1].
Exponents (x^y, e^x):
- For general powers (x to the power of y), enter the base number (x).
- Press the ‘x^y’ or ‘^’ button.
- Enter the exponent (y), then press ‘=’.
- For ‘e’ to the power of x, use the ‘e^x’ button. Enter ‘x’ and then press the function key. This is very useful in calculus and statistics.

You can easily find these powerful features on our web 2.0 scientific calculator. They help you solve difficult math problems quickly.

Using Memory and History Features

The eLearnSmart web 2.0 calc helps you work faster with its memory and history features. These tools let you save results and look back at your calculations. This helps you avoid retyping numbers and keeps your work accurate.

Here are the memory functions:

M+ (Memory Add): Adds the number on the screen to the number in memory.
M- (Memory Subtract): Subtracts the number on the screen from the number in memory.
MR (Memory Recall): Shows the number saved in memory. This will replace the current number on the screen.
MC (Memory Clear): Clears the number saved in memory (sets it to 0).
MS (Memory Store) / STO (Store): Saves the number on the screen to memory. This replaces any number that was already saved.

For example, to calculate (5 * 8) + (7 * 3):

Calculate 5 * 8 = 40.
Press M+ to save 40 in memory.
Calculate 7 * 3 = 21.
Press M+ again. This adds 21 to the memory (memory now has 61).
Press MR to show the total, 61.
Press MC when you are done with the saved number.

Our history feature is also very useful:

Review Past Calculations: The history log saves your past calculations and answers. This lets you check your work or use old answers again without re-typing.
Error Checking: Find and fix mistakes easily by looking at the steps you took.
Efficiency: Copy old results to use in new calculations. This saves a lot of time, especially with long problems.

These smart features make our web 2.0 scientific calculator a great tool for everyone. It’s just one of over 100 free professional calculators on eLearnSmart, each made to help you learn and solve problems.
