Using Exponents to Write Large Numbers By Monica Yuskaitis

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.

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

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

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

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

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

Short Cut for Writing Large Numbers Remember! The exponent is the same as the number of zeros. 2 6 x 10 600 =
