CSF 3.4 Mathematical Operators

Which operator is used to perform addition in programming?

• +

• -

• *

• /

Which operator is used to perform multiplication in programming?

• /

• %

• *

• +

What operator is used to calculate exponentiation (e.g., 3 squared)?

• ^

• **

• //

• %

What does the modulus operator (%) return when used in an expression?

• The quotient

• The remainder

• The product

• The sum

What is the primary function of the negation operator (-) when applied to a single number?

• It subtracts 1 from the number

• It makes the number positive

• It takes the negative of the number

• It divides the number by -1

What is the key difference between a unary operator and a binary operator?

• Unary operators work with one operand, binary with two

• Unary operators are for numbers, binary for text

• Unary operators are always positive, binary can be negative

• Unary operators are faster, binary are slower

What concept determines the order in which different parts of a mathematical expression are evaluated in programming?

• Variable assignment

• Operator precedence

• Data type conversion

• Function definition

According to operator precedence rules, which part of an expression is evaluated first?

• Addition and subtraction

• Multiplication and division

• Exponentiation

• Expressions inside parentheses

In an expression without parentheses, which operations are evaluated before addition and subtraction?

• Only negation

• Only exponentiation

• Multiplication, integer division, and modulus

• All operators are evaluated from left to right

How do mathematical operators generally behave when used with floating-point numbers compared to integers?

• They do not work with floating-point numbers

• They work the same way

• They produce only integer results

• They require special syntax
