Exploring Commutative and Associative Properties of Addition

What did the Cocoloconians discover that allowed them to perform arithmetic calculations?

• Decimal numbers

• Binary numbers

• Roman numerals

• Hexadecimal numbers

What is the result of adding three coconuts and five coconuts?

• Ten coconuts

• Nine coconuts

• Eight coconuts

• Seven coconuts

What does the commutative property of addition state?

• The sum is always zero

• The sum is always negative

• The sum remains the same when the order of numbers is switched

• The sum changes when the order of numbers is switched

Why is subtraction not considered a commutative operation?

• Because it is not a binary operation

• Because it involves only one number

• Because switching the order changes the result

• Because it always results in a positive number

What are the numbers involved in a binary operation called?

• Operands

• Divisors

• Addends

• Factors

What is the result called in an addition operation?

• Quotient

• Sum

• Difference

• Product

How can the commutative property be applied to addition involving more than two numbers?

• By multiplying the numbers

• By adding all numbers at once

• By switching adjacent pairs of numbers

• By subtracting the numbers

What does the associative property of addition illustrate?

• The order of numbers affects the sum

• The sum is always zero

• The grouping of numbers affects the sum

• The grouping of numbers does not affect the sum

What happens when you group positive two and negative two together in an addition problem?

• The sum becomes one

• The sum becomes zero

• The sum becomes negative

• The sum becomes positive

What will be explored in the next few lectures?
