What is the Commutative Property of Addition?

The Commutative Property of Addition states that changing the order of the addends does not change the sum. For example, $$a + b = b + a$$ .

What is the Associative Property of Addition?

The Associative Property of Addition states that the way in which numbers are grouped does not change their sum. For example, $$(a + b) + c = a + (b + c)$$ .

What is the Zero Property of Multiplication?

The Zero Property of Multiplication states that any number multiplied by zero equals zero. For example, $$5 \cdot 0 = 0$$ .

How do you simplify the expression $$8a + 3 + a + 4$$ ?

To simplify, combine like terms: $$8a + a = 9a$$ and $$3 + 4 = 7$$ , resulting in $$9a + 7$$ .

What is an algebraic expression?

An algebraic expression is a mathematical phrase that can include numbers, variables, and operation symbols. For example, $$3x + 2$$ is an algebraic expression.

What is the difference between an equation and an expression?

An equation states that two expressions are equal, using an equal sign (e.g., $$x + 2 = 5$$ ), while an expression does not include an equal sign (e.g., $$3x + 4$$ ).

What does it mean to evaluate an expression?

To evaluate an expression means to calculate its value by substituting the variables with specific numbers. For example, to evaluate $$2x + 3$$ for $$x = 4$$ , substitute to get $$2(4) + 3 = 11$$ .

What is the purpose of using parentheses in algebraic expressions?

Parentheses are used to indicate which operations should be performed first in an expression. For example, in $$(2 + 3) \cdot 4$$ , you perform the addition first.
