Expanded Notation written using the powers of 10 This is an extension of writing the equation in expanded notation! Therefore I will use the information from that to explain; First I'll do out a table showing powers 10^2 = 100 10 to the power of 2 is One Hundred (2 zero's-after the 1) So hopefully you see the pattern in the above table!
Expanded Notation of 20 = (2 x 10) + (0 x 1)
Expanded Notation of 24 = (2 x 10) + (4 x 1)
Expanded Notation of 2,784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
Expanded Notation of 642,275 = (6 x 100,000) + (4 x 10,000) + (2 x 1,000) + (2 x 100) + (7 x 10) + (5 x 1)
Expanded Notation of 3,292 = (3 x 1000) + (2 x 100) + (9 x 10) + (2 x 1).
