# Real number calculator

This calculator makes basic and advanced operations with real, natural, integers, and rational and irrational numbers. It also shows detailed step-by-step information about the calculation procedure. Solve problems with two, three, or more real numbers in one expression. Add, subtract, and multiply real numbers step-by-step. This calculator performs addition, subtraction, multiplication, or division for calculations on positive or negative real numbers. This online real number calculator will help you understand how to add, subtract, multiply, or divide real numbers.

Real numbers are numbers that can be found on the number line. This includes natural numbers( 1,2,3 ...), integers (-3), rational (fractions), and irrational numbers (like √2 or π). Positive or negative, large or small, whole numbers or decimal numbers are all

**real numbers**. Imaginary and complex numbers cannot be drawn in a number line but in a complex plane.

## The result:

### 3*[8-(-1) + (-3)÷(-3)]^2 = 300

### Calculation steps

- Subtract: 8 - (-1) = 8 + 1 = 9
- Divide: -3 / (-3) = 1
- Add: the result of step No. 1 + the result of step No. 2 = 9 + 1 = 10
- Exponentiation: the result of step No. 3 ^ 2 = 10 ^ 2 = 100
- Multiple: 3 * the result of step No. 4 = 3 * 100 = 300
