Calculator parenthesis



sin(pi/2) * (1.1 + 2.2 + 3.3) = 6.6

Calculation steps

  1. Ludolph's number pi; π ≈ 3.14159265
  2. Divide: 3.14159265 / 2 = 1.57079633
  3. sin(the result of step No. 2) = sin(1.57079633) = 1
    We assume trigonometric angle argument in radians.
  4. Add: 1.1 + 2.2 = 3.3
  5. Add: the result of step No. 4 + 3.3 = 3.3 + 3.3 = 6.6
  6. Multiple: the result of step No. 3 * the result of step No. 5 = 1 * 6.6 = 6.6
This calculator makes basic and advanced operations with real numbers, natural numbers, integers, rational and irrational numbers. It also shows detailed step-by-step information about 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 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.
