# Your TI-83 calculator has white lines when you turn on the calculator and when you type numbers the number get cut off. What should you do to get rid of those white lines?

### How do you use a factor tree in prime factorization?

You start by writing the number you have to factorize at the top of the tree. You then draw 2 lines leading off from that number and write 2 factors of the number below the lines. You continue to draw of lines from those numbers until all of the numbers in one line are prime unless they are variables you don't know the equivalent of.

### What is a diagram used to identify the prime factors of a number?

A factor tree is very useful when identifying the prime factors of a number. You draw two lines off of it and write two numbers that multiply together to make that number. If one of the numbers cannot be divided any further, then circle it. That is a prime number. Draw two lines off of numbers that can be divided further, so you have multiple branches dividing off into certain numbers. Once all the numbers…

### What do the lines on a topographical map mean?

These lines represent elivation change on the map. The close the lines are together the steeper that area is. In order to know which direction the change is in you have to look at numbers that should be on the lines. if you find two numbers that are on the same slope and compare them you can tell if it is a hill or a valley that is represented on the map.

### What do you mean by number line?

a number line is a line that shows a pattern in numbers and is in chronological order with the first number which should also be the smallest on the far left side and the highest and last number should be on far right side. number lines can vary in patterens by the data, such as 1,2,3,4,5 or 2,4,6,8,10 or 3,6,9,12,15 and so on but the patteren must be constant NOT like 1,3,4,5,8 or ,9,4,7,2,1

### What is a factor tree look like?

A factor tree is when you take a number and bring it down to prime numbers. You do this by diving the number, and drawing to lines from the number and putting the two numbers that multiply into the starting number. You do that until you have all prime numbers. This skill can be usefull for greatest common factor and lowest commen multiple.

### How do you find the line of symmetry on a calculator?

I have been doing research, and I found there in no way to use a calculator. But, I will list some shapes, and their lines of symmetry. Hexagon,6 lines pentagon,5 lines square,4 octagon,8 circle,never ending/to many to count decagon,10 Notice that the lines of symmetry have the same number as the number of corners. Example, octagon; eight corners, eight sides, eight lines of symmetry. It is like that with all shapes that have sides that…
