Question 20

Identity Elements are…

Answer 20

Operations you can perform on a number that do NOT change the original number

Question 21

What is the Additive Identity?

Answer 21

0
Adding 0 to any number does NOT change the original number

Question 22

What is the Multiplicative Identity?

Answer 22

1
Any number multiplied by 1 remains the same

Question 23

What are Inverse Elements?

Answer 23

Operations performed with a number and an Inverse Element give us the corresponding IDENTITY ELEMENT

Question 24

What is the Additive Inverse for n?

Answer 24

-n
Adding -n to n gives us 0 (the Additive Identity)

Question 25

What is the Multiplicative Inverse for a number, n?
