sin(pi/2) * (1.1 + 2.2 + 3.3) = 6.6
Calculation steps
- Ludolph's number pi; π ≈ 3.14159265
- Divide: 3.14159265 / 2 = 1.57079633
- sin(the result of step No. 2) = sin(1.57079633) = 1
We assume trigonometric angle argument in radians. - Add: 1.1 + 2.2 = 3.3
- Add: the result of step No. 4 + 3.3 = 3.3 + 3.3 = 6.6
- Multiple: the result of step No. 3 * the result of step No. 5 = 1 * 6.6 = 6.6

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.
