In the decimal number system the value of a digit depends on its position in the number. Each position has a value ten times the position to its right. This is unlike other number systems such as Roman numerals. It is this place value that makes arithmetic easier to perform. Make sure you know the position of the digits that represent thousands, hundreds, tens, units, tenths, hundredths and thousandths at least.
Here is an interactive Place Value Chart to help with you calculations.
60 x 70 = 6 x 10 x 7 x 10 = 42 x 100 = 4200
20000 ÷ 500 = 20 x 1000 ÷ 5 ÷ 100 = 4 x 10 = 40
Or 20000 ÷ 500 = 200 ÷ 5 = 40
