Unit 2 -- Logic Review

Identify the hypothesis of:
If 2 + x = 10, then x =  8.

• x = 8
• then x = 8
• 2 + x = 10
• If 2 + x = 10

Identify the conclusion:
Water is freezing implies it is 32 degrees or below.

• Water is freezing
• it is 32 degrees or below
• it might be -30 degrees
• It is 32 degrees or below implies water is freezing.

Identify the conclusion:
Water is freezing implies it is 32 degrees or below.

• Water is freezing
• it is 32 degrees or below
• it might be -30 degrees
• It is 32 degrees or below implies water is freezing.
