How do I convert a number to scientific notation?

Move the decimal point until you have one non-zero digit to the left of it. Count how many places you moved - that's your exponent. If you moved left, the exponent is positive; if right, it's negative.

How do I multiply numbers in scientific notation?

Multiply the coefficients and add the exponents. For example: (2×10³) × (3×10⁴) = (2×3) × 10^(3+4) = 6×10⁷.

How do I add numbers in scientific notation?

First convert to the same power of 10, then add the coefficients. For example: 2×10³ + 3×10² = 2×10³ + 0.3×10³ = 2.3×10³.

What's the difference between scientific and engineering notation?

Scientific notation uses one digit before the decimal (1.5×10⁶). Engineering notation uses exponents that are multiples of 3 (1500×10³), making it easier to relate to metric prefixes like kilo, mega, etc.

Understanding Scientific Notation

Scientific notation expresses numbers as a × 10^n, where a is between 1 and 10, and n is an integer. It's essential for handling very large or very small numbers in science, engineering, and mathematics.

When to Use Scientific Notation

Scientific notation is useful for:

Very large numbers (distance to stars, national debt)
Very small numbers (atomic sizes, microscopic measurements)
Scientific calculations and measurements
Engineering and physics problems
Computer science (floating-point representation)
Astronomy and chemistry
