# How To Do A Cross Product On A TI-83

Cross product mathematics is an advanced binary operation, also known as a vector product. Solving a cross product problem is complex, and is best done with a graphing calculator. While calculators that are capable of 3D graphing are ideal for solving cross products, they are often expensive and impractical for the average consumer. By creating a simple program on the TI-83, you can solve a cross product without a 3D calculator.

### Step 1

Select "PRGM" and "ENTER" to start a new program.

### Step 2

Input "Prompt" by selecting, "PGRM," "Right Arrow" and "2" followed by "A," "B" and "C." Your screen will appear as ":Prompt A, B, C."

### Step 3

Select "ENTER" and repeat the above step while substituting "D," "E" and "F" for the previous letters that were inputted.

### Step 4

Press "ENTER", and input the equation, "AE-BD=Z."

### Step 5

Push "ENTER" again, and input the equation, "CD-AF=Y."

### Step 6

Press "ENTER" and input the final part of the cross product equation, "BF-CE=X."

### Step 7

Input "ENTER", "PRGM," "Right Arrow" and "3", followed by "X,Y,Z."

### Step 8

Code your final line, press "ENTER" and "√(X²+Y²+Z²)."

### Step 9

Save your program by pressing "PRGM" and naming the program "CROSSPRODUCT."
