Properties of Equality Quiz - Ch 7 6th Grade T Douglas

Addition Property of Equality

• If you subtract the same number from each side of an equation, the two sides remain equal.

• If you add the same number to each side of an equation, the two sides remain equal.

• If you multiply each side of an equation by the same nonzero number, the two sides remain equal.

• If you divide each side of an equation by the same nonzero number, the two sides remain equal.

Equation

• A symbol of equality, =.

• A mathematical sentence showing two expressions are equal.

• An expression which is made up of variables and constants, along with algebraic operations.

• Operations which undo each other.

Inverse Operation

• Operations that result in a true sentence when replacing a variable with a value.

• Operations which undo each other.

• A mathematical sentence showing two expressions are equal.

• A symbol of equality, =.

Division Property of Equality

• The two sides no longer remain equal.

• The value of a variable that makes the equation true changes.

• The two sides remain equal if you divide each side by the same nonzero number.

• The two sides remain equal if you multiply each side by the same nonzero number.

Solve an Equation

• To find the value of a variable that makes the equation true.

• To add the same number to each side of an equation.

• To express the equation in terms of another variable.

• To perform the inverse operation on the equation.

Equal Sign

• • -

  • A sign of difference

• • *

  • a sign of something new

• =

  a sign of equality

• /

  a sign of parts and pieces

Multiplication Property of Equality

• Add the variable to both sides of the equation
• Subtract the variable from one side of the equation
• If you multiply then your answer will increase in value

• If you multiply each side of an equation by the same nonzero number, the two sides remain equal.

Solution

(mathematically speaking)

• A numerical coefficient that multiplies a variable.

• The point where a line crosses the y-axis.

• Value of a variable that makes an equation true.

• An arbitrary placeholder used to represent a number in equations.

Subtraction Property of Equality

• If you subtract a number from both sides of an equation, the equality is maintained.

• Add the same number to both sides of the equation.

• Divide both sides of the equation by the same number.

• Multiply both sides of the equation by the same number.
