## Scientific notation

### Plato

Plato was a philosopher from Greece

Born in 427 BC

Born into wealthy family

Influenced by Socrates

### Lesson

• Scientific notation is used to express the size of really big numbers such as

• 1,111,000,000,000

• Or really small numbers like this

• 0.00000000000012

• The way the first & second number would look is this

• 1.111x10¹² 1.2x10¯¹³

### Explanation 1

• You can do this by if the number is in standard form exp. 1,000,000 just count how many decimal places to the LEFT (if it’s a whole number) until you get the decimal behind the first number

### Explanation 2

• You’re probably are wondering why the decimal has a negative exponent its because they are less then one and need to use numbers to represent numbers less than one exp.

• 0.00009 is less than 1.00000

• 1,000

• 3.0x10³
