Worked Examples

Worked Example 1

Expanded Form Two Ways

Write 306,450 in expanded form.
  1. 1The digits are 3 hundred thousands, 0 ten thousands, 6 thousands, 4 hundreds, 5 tens, and 0 ones.
  2. 2With values: 300,000 + 6,000 + 400 + 50
  3. 3With multiplication: (3 × 100,000) + (6 × 1,000) + (4 × 100) + (5 × 10)
Answer: 300,000 + 6,000 + 400 + 50

Worked Example 2

Word Form to Standard Form

Write five hundred twelve thousand thirty-eight in standard form.
  1. 1Five hundred twelve thousand is 512,000.
  2. 2Thirty-eight is 38, so the hundreds digit is 0.
  3. 3512,000 + 38 = 512,038
Answer: 512,038

Common Mistakes to Watch For

Leaving out zeros

Wrong:forty thousand six = 4,006

Forty thousand is 40,000. Add 6 ones: 40,006.

Using the wrong place in expanded form

Wrong:The 7 in 700,000 written as 7 × 10,000

The 7 in 700,000 is in the hundred thousands place: 7 × 100,000.

Helpful Math Tip

Read the number in two parts, split at the comma: say the thousands part, then the word "thousand," then the rest.
