Mathematical Formulas Used in the Calculator
The Ba2 Plus Professional Calculator supports several mathematical formulas. Understanding these formulas can help you select the correct function and interpret the results.
1. Addition Formula
Addition combines two or more numerical values to produce a total.
\[ S=a+b \]
Where:
- S = Sum.
- a = First number.
- b = Second number.
Example:
\[ S=45+35=80 \]
2. Subtraction Formula
Subtraction determines the difference between two numbers.
\[ D=a-b \]

3. Multiplication Formula
Multiplication calculates the product of two numbers.
\[ P=a\times b \]
Example:
\[ P=12\times15=180 \]
4. Division Formula
Division determines how many times one number can be divided by another.
\[ Q=\frac{a}{b} \]
Where b must not equal zero.
Example:
\[ Q=\frac{120}{10}=12 \]
5. Percentage or Modulo Operation
The calculator’s % operator calculates the remainder after division rather than a conventional percentage of a number.
Its mathematical representation is:
\[ R=a\bmod b \]
Example:
\[ 17\bmod5=2 \]
The remainder is 2 because 5 goes into 17 three times, leaving 2.
6. Square Formula
A square is calculated by multiplying a number by itself.
\[ A=x^2 \]
Example:
\[ A=9^2=81 \]
7. Power Formula
Exponentiation raises a base number to a specified power.
\[ P=x^y \]
Where:
- x = Base.
- y = Exponent.
Example:
\[ P=2^5=32 \]
8. Square Root Formula
The square root determines the number that produces the original value when squared.
\[ x=\sqrt{a} \]
Example:
\[ \sqrt{225}=15 \]
9. Trigonometric Formulas
The primary trigonometric functions are defined as follows for an angle θ in a right-angled triangle:
\[ \sin\theta=\frac{\text{Opposite}}{\text{Hypotenuse}} \]
\[ \cos\theta=\frac{\text{Adjacent}}{\text{Hypotenuse}} \]
\[ \tan\theta=\frac{\text{Opposite}}{\text{Adjacent}} \]
These functions are useful for calculating angles, distances, heights, and relationships between sides of triangles.
10. Logarithm Formula
A logarithm determines the exponent required to produce a particular number.
\[ \log_b(x)=y \]
This means:
\[ b^y=x \]
For the calculator’s common logarithm function, the base is 10.
Example:
\[ \log_{10}(10000)=4 \]
11. Natural Logarithm Formula
The natural logarithm uses Euler’s number as its base.
\[ \ln(x)=y \]
This means:
\[ e^y=x \]
Example:
\[ \ln(e^3)=3 \]
12. Factorial Formula
The factorial of a nonnegative whole number is the product of all positive integers up to that number.
\[ n!=n(n-1)(n-2)\cdots1 \]
The special case is:
\[ 0!=1 \]
Example:
\[ 6!=6\times5\times4\times3\times2\times1 \]
\[ 6!=720 \]
13. Reciprocal Formula
The reciprocal of a nonzero number is calculated by dividing one by that number.
\[ R=\frac{1}{x} \]
Example:
\[ R=\frac{1}{4}=0.25 \]
14. Exponential Formula
The exponential function raises Euler’s number to a specified power.
\[ f(x)=e^x \]
Example:
\[ e^2\approx7.3891 \]
15. Base-10 Exponential Formula
The ten-power function calculates 10 raised to a specified exponent.
\[ f(x)=10^x \]
Example:
\[ 10^3=1000 \]
Practical Examples of Using the Ba2 Plus Professional Calculator
The following examples demonstrate how the calculator can help with different mathematical problems.

\[ 25+40+35 \]
Calculation:
\[ 25+40+35=100 \]
Result: $100
This is a simple example of using the calculator for shopping expenses, budgeting, and everyday arithmetic.
Example 2: Calculate the Square Root
Suppose you need to calculate the square root of 625.
Enter 625 and select the square root function.
Formula:
\[ \sqrt{x} \]
Calculation:
\[ \sqrt{625}=25 \]
Result: 25
This function is useful in geometry, algebra, and mathematical exercises.
Example 3: Calculate a Trigonometric Value
Suppose you want to calculate the sine of 30 degrees.
First, select DEG mode.
Then enter 30 and press the sine function.
Formula:
\[ \sin(30^\circ)=0.5 \]
Result: 0.5
This calculation is useful in geometry, physics, construction, and engineering.
Example 4: Calculate a Factorial
Suppose you want to calculate the factorial of 7.
Enter 7 and select the factorial function.
Formula:
\[ 7!=7\times6\times5\times4\times3\times2\times1 \]

\[ 10^4=10000 \]
Result: 10,000
This is useful for scientific notation and large-number calculations.
Understanding Degree and Radian Modes
One of the most important features of a scientific calculator is the ability to work with different angle measurement systems.
The Ba2 Plus Professional Calculator provides DEG and RAD modes.
What Is Degree Mode?
Degree mode measures angles using degrees. A complete circle contains 360 degrees.
For example:
- 90° represents a right angle.
- 180° represents a straight angle.
- 360° represents a complete rotation.
When working with common geometry and school-level trigonometry problems, degree mode is frequently used.
What Is Radian Mode?
Radian mode measures angles using radians. A complete circle contains \(2\pi\) radians.
The relationship between degrees and radians is:
\[ 180^\circ=\pi\text{ radians} \]
To convert degrees into radians:
\[ \text{Radians}=\text{Degrees}\times\frac{\pi}{180} \]
To convert radians into degrees:
\[ \text{Degrees}=\text{Radians}\times\frac{180}{\pi} \]
For example:
\[ 90^\circ=\frac{\pi}{2} \]
Both measurement systems are mathematically valid. The correct selection depends on the equation or problem you are solving.
