Quick Reference
Standard Notation
Numbers written with commas as thousands separators and decimal points (e.g., 5,786.04)
Scientific Notation
Numbers written as a × 10^b where 1 ≤ a < 10 and b is an integer
Exponential Notation
Numbers written with 'e' or 'E' (e.g., 1.23e5 = 1.23 × 10^5)
Conversion Rules
Quick Tips
Standard notation shows the actual value without exponents
Use commas every three digits for readability
Scientific notation is useful for very large or small numbers
Both notations represent the same value
Understanding Standard Notation
What is Standard Notation?
Standard notation (or standard form) displays values with commas every three positions and a period as a decimal point, such as 5,786.04. The number has a regular place-value form with no multiplication signs or exponents.
Place Value
The value of each digit depends on its position. For example, in 2,698, the 2 has a value of 2 thousand, while in 3,412,000, the 3 represents 3 million.
Converting from Scientific Notation
Step 1: Identify Exponent
Find the power of 10 in the scientific notation
Step 2: Move Decimal
Move decimal point by the number of places indicated
Step 3: Add Zeros
Fill empty spaces with zeros as needed
Step 4: Format
Add commas for thousands separators
Powers of 10 Operations
Multiplication by Powers of 10:
Move the decimal point to the right by the same number of places as the exponent.
780 × 100 = 78,000
Division by Powers of 10:
Move the decimal point to the left by the same number of places as the exponent.
0.08 ÷ 1,000 = 0.00008
