Topic: Expanding Numbers

To expand a number we write the place value for each digit. For example:

a. 19 = 10 + 9 (1 ten + 9 ones)
b. 329 = 300 + 20 +9 (3 hundreds + 2 tens+ 9 ones)
c. 163 = 100 + 60 + 3 ( 1 hundred + 6 tens + 3 ones )
d. 5, 780 = 5,000 + 700 + 80 (5 thousands + 7 hundreds + 8 tens)
