Subtraction place value is a strategy to subtract easier.
To solve a problem using subtraction place value. First I spit the second number.
Example: 64-21 21=20+1
Next I took away the ones from the number 21. So 64-1=63.
After that I took away the tens. I also use the 63. So 63-20=43
The answer to 64-21 = 43.
