**Using Exponents to Write Large Numbers**

By Monica Yuskaitis

2
**For Learning to Happen! Clear your desk of anything that may**

distract you. Remove all other thoughts from your mind. Pay close attention. Try all the examples. Ignore all other distractions.

3
**What Is the Standard Form**

Exponents of Ten What Is the Standard Form of These Tens? 2 100 10 3 1,000 4 10,000 5 100,000

4
Exponents of Ten Notice that the number of zeros matches the exponent number 2 100 10 3 1,000 4 10,000 5 100,000

5
**Multiplying Multiples of Ten**

Multiply These Numbers 100 x 2 = 200 1,000 x 3 = 3,000 10,000 x 7 = 70,000 100,000 x 9 = 900,000

6
**Multiplying Multiples of Ten**

Did you notice that all you have to do is multiply 1 x whole number & add the zeros behind? 100 x 2 = 200 1,000 x 3 = 3,000 10,000 x 7 = 70,000 100,000 x 9 = 900,000

7
**Short Cut for Writing Large Numbers**

Combine these two steps for writing large numbers. 6 x 10 2 600 = 6 x (10 x 10) = 6 x 100 = 600

8
**Short Cut for Writing Large Numbers**

Remember! The exponent is the same as the number of zeros. 2 6 x 10 600 =
