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 / 2 + pi/2 = 0.07079632679
Calculation steps
- Divide: -3 / 2 = -1.5
- Ludolph's number pi; π ≈ 3.14159265
- Divide: 3.14159265 / 2 = 1.57079633
- Add: the result of step No. 1 + the result of step No. 3 = -1.5 + 1.57079633 = 0.07079633
