Exploring the Properties of Equality

What is the addition property of equality?

• Dividing the same number to both sides of an equation keeps it equal.

• Adding the same number to both sides of an equation keeps it equal.

• Subtracting the same number from both sides of an equation keeps it equal.

• Multiplying the same number to both sides of an equation keeps it equal.

If you have 5 + 3 = 8 and subtract 2 from both sides, what is the new equation?

• 5 + 3 / 2 = 8 / 2

• 5 + 3 - 2 = 8 - 2

• 5 + 3 + 2 = 8 + 2

• 5 + 3 * 2 = 8 * 2
