• A number
3. WHAT are true or false statements?
Week #1A Section #1 Notes Integers and True/False Statements The Questions
• 2. WHAT kind of answer should you ALWAYS have for a evaluate problem?
• A number
3. WHAT are true or false statements?
A true statement is an equation that is the same thing on both sides.
(Like 4 + 1 = 5) With a false statement, the sides are different. (Like 4 + 1 = 6)
