Dimensional Analysis
• Dimensional Analysis: A way to convert units by using fractions that represent the conversion ratios.
• Steps for Dimensional Analsys:1. Write the original Value as a Fraction
2. Create a new fraction beside the original, place the units on the new fraction to cancel out the original unit.
3. Place the conversion numbers beside the matching unit.
4. Repeat steps 2 and 3 until you have converted to the appropriate unit.

Scientific Notation• Scientific Notation: A way to write a number using powers of ten.
Steps to Writing Scientific Notation.1. Create the digit by moving the decimal to create a number that is BEWTEEN 1
and 10.
2. Multiply by 10.
3. Count the number of places the decimal has moved, a create the exponent for 10.
4. Moved Left = Positive, Moved Right = Negative.
