## Study Notes

### PEMDAS Order of Operations

#### Parentheses

- Evaluate expressions inside parentheses first
- Follow the order of operations inside the parentheses
- Evaluate expressions from innermost to outermost parentheses

#### Exponents

- Evaluate any exponential expressions next (e.g. 2^3)
- Evaluate from right to left in case of multiple exponents

#### Multiplication And Division

- Evaluate multiplication and division operations from left to right
- In case of multiple operations, perform the one that appears first from left to right

#### Addition And Subtraction

- Evaluate addition and subtraction operations from left to right
- In case of multiple operations, perform the one that appears first from left to right

### PEMDAS Order of Operations

### Evaluating Expressions

- Evaluate expressions inside parentheses first, following the order of operations within them
- Evaluate expressions from innermost to outermost parentheses

### Exponents

- Evaluate exponential expressions next, such as 2^3
- Evaluate exponents from right to left in case of multiple exponents

### Multiplication and Division

- Evaluate multiplication and division operations from left to right
- Perform the operation that appears first from left to right in case of multiple operations

### Addition and Subtraction

- Evaluate addition and subtraction operations from left to right
- Perform the operation that appears first from left to right in case of multiple operations

### PEMDAS: Order of Operations

- PEMDAS is a mnemonic device that helps remember the order of operations in mathematics, standing for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

### Order of Operations

- Evaluate expressions in the following order:
- Expressions inside
**Parentheses**first -
**Exponents**next -
**Multiplication and Division**operations from left to right -
**Addition and Subtraction**operations from left to right

- Expressions inside

### Exponents

- Exponents are a shorthand way of writing repeated multiplication
- Example: 2Â³ means 2 multiplied by itself 3 times: 2 Ã— 2 Ã— 2
- Exponents are evaluated after parentheses, but before multiplication, division, addition, or subtraction operations

### Parentheses

- Parentheses group numbers and operations together
- Evaluate expressions inside parentheses first, following the order of operations within the parentheses
- Example: 2 Ã— (3 + 4) means to evaluate the expression inside the parentheses first: 2 Ã— 7 = 14
