In a number with a decimal point, if you move the decimal point to the right, it's the same as multiplying by a power of ten. If you have some scientific notation where you're multiplying by ten to a power, then you move the decimal place to the right the number of spaces of the exponent. On the other hand, if you move a decimal place to the left, it is like dividing by ten, or multiplying by ten to the negative one power. If you're given scientific notation with ten to a negative power, move your decimal point that many spaces to the left. In each case, you might need to fill in some zeros.
