If we are moving from a large value to a small value we move the decimal point to the left.
to the left
Moving from a smaller value to a larger value.
Number to a multiple by a positive power of 10.
Moving from a smaller value to a larger value.
The magnitude or value of the number.
Move the decimal point one place to the right. If the decimal point is already at the end of the number, add a 0 to the extreme right before moving the decimal point.
8.0 x 10-7To write this in standard form we need to have one digit (not a 0) in front of the decimal point. We can do this here by moving the decimal point 7 places to the right. As we are moving the decimal point 7 places to the right we are making the number 107 times as large. Therefore we need to multiply by 10-7 to get back to the original number.
