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

Exponents of Ten Notice that the number of zeros matches the exponent number 2 10 3 10 4 10 5 10 100 1, 000 100, 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. 2 6 x 10 = 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
