Real number calculator



Result:

3*[8-(-1) + (-3)÷(-3)]^2 = 300

Calculation steps

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

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 the 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 numbers and complex numbers cannot be draw in number line, but in complex plane.

Examples:

addition of real numbers: -3/2 + pi/2
subtraction of real numbers: 32.14 - 67.32
parenthesis: sin(pi/2) * (1.1+2.2+3.3)
Complex example: Priority of operators and brackets: 3⋅[8−(−1) + (−3)÷(−3)]^2
