She has seen teachers, students and parents conquer their math phobia. She has supported math teachers in BC, AB, ON, NB, NS, FL and NY. Scientific Notation Rules If the given number is multiples of 10 then the decimal point has to move to the left, and the power of 10 will be positive. She has helped students and parents learn to love math. 2-2 Powers of Ten and Scientific Notation Numbers are usually written in standard form. Since being introduced to Power of Ten by Trevor Calkins in the late 1990s, Anita transformed her approach to teaching math. For powers of ten with positive exponents, move the decimal point to the right. The decimal point has been moved $6$ places to the right so the exponent of the power of $10$ is $-6$. 2-2 Powers of Ten and Scientific Notation Course 2 You can also find the product of a number and a power of ten simply by moving the decimal point of the number.After moving the decimal point, so the number has one digit in front of the decimal point, the number is $9.205$ (this number is between $1$ and $10$).The number in scientific notation is $6.24\times 10^5$.The decimal point has been moved $5$ places to the left so the exponent of the power of $10$ is $5$.After moving the decimal point, so the number has one digit in front of the decimal point, the number is $6.24$ (this number is between $1$ and $10$).Write the number $624000$ in scientific notation. Put the number in the correct pattern for scientific notation.If the original number is small, you have moved the decimal point to the right, and the exponent of the power of 10 is the negative integer of the number of places you moved the decimal point.

If the original number is large, you have moved the decimal point to the left, and the number of places you moved the decimal point is the exponent of the power of 10.The exponent of the power of 10 is determined by the number of places you have moved the decimal point.Move the decimal point until there is one (non-zero) number in front of the decimal point.To convert numbers into scientific notation: One strategy is provided in this module.Ī number written in scientific notation is written as a number between $1$ and $10$ multiplied by a power of $10$. Similarly, when you are converting a large number to a standard form (scientific notation), the power of ten would be positive. Hence, when you are converting them to standard form, the power of ten is negative.

Step 3: Represent the numbers up to the last non-zero digit only. 7 8 × 1 0 8 Negative exponents: Decimal numbers have small values. Step 2: Count the digits after the decimal point and raise this value as a power of ten. There are many strategies to convert numbers into scientific notation and to reverse the process. Solution: Step 1: Identify the first non-zero digit and place the decimal point after this number.
