Answer:
Step-by-step explanation:
I just know and there isn't really a way to explain, except to show where each place value is.
EXAMPLE NUMBER: 12,345
The 1 is in the place value of ten-thousands.
The 2 is in the place value of thousands.
The 3 is in the place value of hundreds.
The 4 is in the place value of tens.
The 5 is in the place value of ones.
Memorise this, and place value problems will be very easy:)
