Understanding Expressions and Order of Operations

What is the main difference between an expression and an equation?

• Expressions are always solved first.

• Expressions always include inequality signs.

• Expressions contain an equal sign.

• Expressions do not contain an equal sign.

In the expression 12 / 4 + 2, if the parentheses are around 12 / 4, what is the result?

• 3

• 6

• 5
