To find the difference between two numbers, we simply subtract the smaller number from the larger number.
Step 1: Define the Numbers
We are given two numbers:
\[
\text{num1} = 723
\]
\[
\text{num2} = 285
\]
Step 2: Subtract the Smaller Number from the Larger Number
To find the difference, we subtract the smaller number from the larger number:
\[
\text{difference} = \text{num1} - \text{num2}
\]
\[
\text{difference} = 723 - 285
\]
