Question 1 options:

If a > b, then a - c > b – c

If a = b, then a + c = b + c

If a = b, then c ∙ a = c ∙ b

If a = b, then a - c = b - c

Whenever you add or subtract like terms to simplify an equation or inequality.

The reason or explanation for each step in a proof.

a(b + c) = ab + ac

An algebraic relation showing that a quantity is "greater than" or "less than" another quantity.

If a > b, then a + c > b + c

If a = b, and c ≠ 0, then a/c = b/c

An equation or inequality containing one or more variables.


A method to prove statements using properties that justify each step.

If a > b, and c > 0, then a/c > b/c
If a > b, and c < 0, then a/c < b/c

Any and all values of the variable that satisfies an equation or inequality.

If a > b, and c > 0, then c ∙ a > c ∙ b
If a > b, and c < 0, then c ∙ a < c ∙ b
