What is the difference between an equation and an expression?

• There is no difference

• An equation has an answer and an expression could have an answer.

• Equation can only have one term after the equals sign and an expression could have one or more terms after the equals sign.

• An expression we do not know what one quantity is equal to and an equation we know what one quantity is equal to another quantity.

What does an EQUATION have that an EXPRESSION does not?

• Symbol ( x, -, +, /)

• Equal Sign

• They are the same thing

• Parentheses

SOLVE: 8(t + 3) = 64

• t = 5

• t = 8
