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
    Assuming 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
