   Subtract Whole Tens
    
   Step 1: Think in Groups of Ten
   When you have a subtraction problem involving whole tens (like 90−40), you can temporarily ignore the zeros and focus only on the tens digit.
   90 is 9 tens.
   40 is 4 tens.
   The problem becomes a simple single-digit subtraction:
   9 tens − 4 tens = __tens
    
   Step 2: Solve the Basic Subtraction
   Solve the subtraction problem using the tens digits:
   9−4=5
   This tells you the answer will be 5 tens.
    
   Step 3: Convert Back to the Whole Number
   The final step is to convert the tens count back into its whole number form.
   5 tens is equal to 50.
   So, the final answer is:
   90−40=50
