: THERE IS A SYMBOL IN THIS CHAPTER THAT I AM NOT TO FAMILIER WITH. THE EXPLANTION FOR RATIONAL NUMBERS SAYS THAT IT IS ANY NUMBER THAT CAN BE WRITTEN IN THE FORM A/B WHERE A AND B ARE INTEGERS AND B=0. I CANT MAKE THE SYMBOL ON THE COMPUTER BUT I AM GOING TO DESCRIBE IT TO YOU. IT IS A = SIGN WITH A SLANTED LINE THROUGH THE CENTER OF IT. I THINK IT MEANS EQUAL BUT I AM NOT SURE. This question is from textbook intermiate algebra

An equals sign (=) with a back slash means: "Is not equal to"
In your explanation for a rational number,it is telling you that a rational number is any number that can be expressed as a ratio of two integers, A/B, where B cannot equal zero.
This is because if B were zero you would have division by zero which, as you probably are aware, is undefined in mathematics.

The symbol you have described means "not equal to".
.
You are given and are told that B "is not equal" to zero. Why can B not be equal
to zero??? Because in algebra division by zero is not allowed.
.
Hope this helps you to understand what the textbook means by the sign you described.
