4.75 times 5.99 = simple calculation

4.75x5.99=(5-0.25)x5.99=5x(6-0.01)-0.25x(6-0.01)=30-0.05-1.5+0.0025=28.4525

The negative square of three plus the cube of eight is the absolute value of three minus five

-4

A = (B-C) / Σ|d-e | × 100%. I want to ask this operation order is B-C divided by Σ and then multiplied by the absolute value
a=(b-c)/∑|d-e|×100％
I want to ask if the order of operation is B-C divided by Σ and multiplied by absolute value or B-C divided by (Σ multiplied by absolute value). I'm a little confused

Σ is the sum sign, the sum of all the following terms
Please accept, thank you
I hope it will help you
