## GED Tutorial

#### Intro

I know that there are multiple subjects on the GED (math, science, social studies, reading, and writing), and they can be difficult to prepare for. Khan Academy is a great way to get a visual and auditory lesson on subjects. However, the test taking process can be anxiety provoking. Being prepared for the GED is one of the most important parts of stepping up to take the test. Remembering important rules for math, for example, is a way to be confident while taking the test.

#### Sample Problem

The communicative property of addition states n (number) + n = sum

The communicative property of multiplication states n * n = product

Therefore, when doing operations in algebra take caution when balancing an equation such as 2x + 4 = 7

#### Solution

Step 1) Get ‘x’ alone by first subtracting 4 from both sides

2x + 4 = 7

4 – 4= 0 and 7 – 4 = 3

2x = 3

Step 2) Get ‘x’ alone next by dividing the number attached to it (2) from both sides.

2x = 3

2 / 2 = 1 and 3 / 2 = 1.5
Step 3) Simplify

x=1.5

Step 4) Check your work. The communicative rule of multiplication allows you to either do 1.5 * 2 or 2 * 1.5.

2(1.5) + 4 = 7

3 + 4 = 7

And the communicative property of addition states that 3 + 4 = 7 and 4 + 3 = 7.
