Example Question #5 : How To Define Integers In Pre Algebra
Which of the following is not an integer?
Integers are all counting numbers, and include both 
Example Question #61 : High School Math
What is the difference between 8 and -2?
-6
6
10
-10
4
10
Since we want to find the difference between 8 and -2, we want to subtract -2 from 8. Since subtracting is equivalent to adding the same number with the opposite sign, we have the below:
Example Question #62 : High School Math
Find the difference.
We are subtracting here, so it is important to remember that subtracting is really just adding the same number with opposite sign. Thus we can think of the problem as the following:
Example Question #63 : High School Math
What is 
Recall that subtracting integers is equivalent to adding the inverse. The inverse of a negative number is the positive number with the same magnitude.
Thus, our problem is equivalent to 
Example Question #64 : High School Math
Evaluate the following expression:
Recall that subtracting is equivalent to adding the inverse:
The inverse of a negative number is a positive number:
Example Question #62 : High School Math
What is:
Recall the placement of numbers on the number line. 
When we add these spaces we end up going 
Example Question #65 : High School Math
What is 
Recall that subtracting a negative number is equivalent to adding the opposite. Thus,
Example Question #66 : High School Math
What is 
Recall that subtracting negative numbers is equivalent to adding the opposite. Then, we have that:
Example Question #1 : How To Multiply And Divide Integers In Pre Algebra
Solve the expression below.
In this case, it is key to recall the rules for multiplying or dividing with negative values.
Negative * Positive = Negative
Negative * Negative = Positive
Positive * Positive = Positive
In this case, we are multiplying two negative numbers; thus the answer should be a positive number. To find the value, we can simply multiply the terms without their negatives.
Example Question #2 : How To Multiply And Divide Integers In Pre Algebra
Simplify:
First multiply all the numbers 
If there is an even amount of negative signs, then the product will be positive. If there is an odd amount of negative signs, then the product will be negative.
Therefore, the answer is
