Properties
What is Addition Property of Inequality
if the same amount is added to both sides of an inequality, then the inequality is still true
Inequality
the relation between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”
Addition Property of Equality
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equ
Division Property of Inequality
if you divide one side of an inequality by a number, you can divide the other side of the inequality by the same number
Equation
a statement that the values of two mathematical expressions are equal (indicated by the sign =).
defining a variable
a quantity that may change within the context of a mathematical problem or experiment
Multiplication Property of Inequality
if you multiply one side of an inequality by a number, you can multiply the other side of the inequality by the same number.
Solution
A value or values which, when substituted for a variable in an equation, make the equation true
Division Property of Equality
when we divide both sides of an equation by the same non-zero number, the two sides remain equal
Subtraction Property of Inequality
if the same number is subtracted from both sides on the inequality then the sense (equality symbol) of the inequality remains unchanged
two-step equation
an algebraic equation that takes you two steps to solve
Multiplication Property of Equality
when we multiply both sides of an equation by the same number, the two sides remain equal
Inverse Property of Multiplication
if you multiply a number by its reciprocal, also called the multiplicative inverse, the product will be 1.
two-step inequality
undo the addition or subtraction first, using inverse operations, and then undo the multiplication or division
Expression
In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)
