• Rules- units must cross out except the last one on the top!
• If a number is on top then multiply it
• If a number is on the bottom then divide it

What is scientific notation?
For scientific notation leave one number (not a zero) in front of the decimal and then put times 10 and raise it to a power.
What power? Count how many times you had to move your decimal. That is the number you raise it too
Check your negatives and positives
