Calculations in one field

[HusamJubeh]

Hello all
I have four calculations, the final result of which is the field value.
Can you help me write it in Python 3?

A = abs(!AREA_RECORD! - !Shape_Area!)
B = 0.8*math.sqrt(!AREA_RECORD!)+0.002* !AREA_RECORD!
C= abs(B- A)
D = B - C
print D

Thanks

Hope this helps,

If you're running this in 'Calculate Field', this will be the format. In Code Block,

import math

def calculate_D(AREA_RECORD, Shape_Area):
    A = abs(AREA_RECORD - Shape_Area)
    B = 0.8 * math.sqrt(AREA_RECORD) + 0.002 * AREA_RECORD
    C = abs(B - A)
    D = B - C
    return D

Expression:

calculate_D(!AREA_RECORD!, !Shape_Area!)

For example,
