It took me forever to learn scientific notation because of how the exponents seem backwards.

When you move the decimal to the left (towards the negative numbers in a line) your exponent will be positive. When you move the decimal to the right (towards the positive numbers in line) your exponent will be negative.

So since we need a number between 1-9 in order have scientific notation we have to move our decimal one place to the left.

10.4 -> 1.04 x 101
