-The fourth power of 1 - (1,2-2,3) divided by the third power of 1,3 * [- 2 - (- 3)] - | 0.5-2|

-The fourth power of 1 - (1,2-2,3) divided by the third power of 1,3 * [- 2 - (- 3)] - | 0.5-2|

The original formula = - 1 - (3 / 6 - 4 / 6) × 3 × (- 2 + 27) - | 0.5-4|
=-1 +(1/6)×3×25 - 3.5
=-4.5+ 25/2
=-4.5+ 12.5
