To solve the subtraction problem, we need to subtract the second number from the first number. This will give us the difference between the two weights.
Step 1: Identify the Given Values
We are given two weights: \( 56.000 \, \text{kg} \) and \( 36.000 \, \text{kg} \).
Step 2: Perform the Subtraction
To find the difference between the two weights, we subtract the second weight from the first weight:
\[
56.000 - 36.000 = 20.000
\]
Final Answer
The difference between the two weights is \(\boxed{20.000 \, \text{kg}}\).
