Properties of Numbers: Additive Identity Property of Addition

The video tutorial begins by discussing the enjoyment of eating ice cream, which is often served by the scoop. A scenario is presented where a person has two scoops of ice cream and is asked if they want another, to which they decline, illustrating that the number of scoops remains the same. This leads to an explanation of the additive identity property in mathematics, which states that adding zero to a number does not change its value. The concept is further clarified with an example of adding zero to 78, resulting in a sum of 78.

How many scoops of ice cream does the person have after declining an additional scoop?

• 1 scoop

• 4 scoops

• 3 scoops

• 2 scoops

What mathematical property explains why the number of scoops remains the same when zero is added?

• Commutative Property

• Additive Identity

• Additive Inverse

• Multiplicative Identity

If you have 78 and add zero to it, what is the result?

• 80

• 100

• 78

• 0

Which of the following numbers will remain unchanged when zero is added to it?

• All of the above

• 78

• 0

• 45

What is the sum of 100 and zero according to the additive identity property?

• 50

• 0

• 100

• 200
