This lesson introduces students to algebraic equations.
• To be able solve simple algebraic equations.
Algebraic equations allow you to solve for an unknown. For example, if you have $62 and you want to buy a game that costs $79, how much more money do you need? You could write this as an algebraic equation in order to find you answer:
62 + x = 79
In order to solve the problem, you need to get x to be by itself. In order to do this, you would need to get the 62 on the left to be on the other side of the = sign. When you move a number from one side of the equals sign to another, you need to perform the opposite operation of the original. In other words, since 62 is a positive number, you would need to make it a negative number when you move it to the other side of the equals sign.
