What is the numeric expression that represents this problem: one-half of the square of the sum of -2.4 and 16.7, subtracted from the square of the diffrence of 3 and 15?

Sum of  16.7 - 2,4 =14.3 square it:

14.3^2 =204.49  divide it by 2

204.49 / 2 =102.245............(1)

 

15  -  3  =12  square it

12^2  = 144.........................(2) 

Subtract  (1) from (2)

144  -  102.245  = 41.755
