February 25: Operations with Scientific Notation

Today was a short day because of Career Day, so we quickly went over how to multiply and divide numbers in Scientific Notation.

1.  Rule for Multiplying:

(c × 10^a) × (d × 10^b)  = (c × d) × 10^a+b

Multiply the factors and the ADD THE EXPONENTS 

2.  Rule for Dividing:

(c × 10^a) ÷ (d × 10^b) = (c ÷ d) × 10^a-b

Divide the factors and then SUBTRACT THE EXPONENTS

Remember we have our Unit 6 test THIS FRIDAY!
