(9 cards)
What do arithmetic expressions involve?
Mathematical symbols or keywords for operations
Keywords like Calculate and Compute are used
What are the basic arithmetic operators?
- /
The division operator can be combined with modulus (mod) or integer division ()
What is the purpose of parentheses in arithmetic expressions?
To control the order of evaluation
They can change the standard order of precedence
List the standard order of precedence for arithmetic operations.
- Parentheses
- Exponentiation (^)
- Negation (Not) (-)
- Multiplication (*) and Division (/)
- Integer Division () and Modulus (mod)
- Addition (+) and Subtraction (-)
Operations with higher priority are evaluated first

- Assign a value to a variable
- Replace the value of a variable
Example: total = 0 and Sum = sum + points
Fill in the blank: The division operator can be combined with _______ or integer division.
