An expression is a math sentence with numbers and symbols, but no equals sign. An equation has an equals sign and shows two things are the same.
Equations help you solve for unknowns, like figuring out how much money you need to buy a game after saving some allowance.
Remember, whatever you do to one side of the equation, do to the other!
\[x + 5 = 12\]
If x + 7 = 10, then x = 3.
Expression: 3y + 2. Equation: 3y + 2 = 11.
Equations help us find unknown values, while expressions show relationships between numbers.
