The Keys to Learning Basic Algebra

Convinced that learning basic algebra is far from basic?  These 3 key algebraic concepts will make life a lot easier.

Up until the time you reached algebra, the equal sign, =, was probably used as a way of signifying the answer to a problem.  Now that we are growing into higher levels of math, the equal sign will now be used as a way of separating the two sides of an equation.

The easiest way to determine if you have an expression or an equation is by asking yourself this question:  "Does my problem have an equal sign in it?"  If the answer to this question is yes, then you have an equation.  Look, the word equation has the first four letters of the word equal right in it.  *Remember, equations have equal signs, expression don't.*

Expressions need simplified - we do this by combining like terms.  A "like term" is a number that has the same letter attached to it.

Examples:

To give expressions more meaning, you can give each letter a name.

     Let x stand for x-box (or x-ray, whatever you want...)

Looking back at the first expression above, it should make sense to you that "3 x-box's plus 2 x-box's makes 5 x-box's."

Another Example: 

3x + 4y
Is NOT 7x or 7y  - leave it as 3x + 4y
Let x stand for x-box and y stand for yoohoo

Remember, 3 x-box's and 4 yoohoo's cannot combine!  In terms of math, leave the expression 3x + 4y as it is - you cannot simplify it.

One More Example:

Equations have equal signs.  This means that your answer should also have an equal sign in it - like x = 4.  Being able to properly solve equations is essential to learning basic algebra.

The equal sign in an equation separates the two sides of the equation into the left hand side (LHS) and the right hand side (RHS).  Viewing the equal sign as a divider instead of an answer mark is essential to learning basic algebra. 

Each side of the equation is actually an expression.  Simplify each expression first if it is possible.  Take a look back at the lesson on combining like terms if you are unsure.
