Example Question #161 : Real Numbers
Solve.
First, let's work from left to right. A plus and minus sign make a minus sign. Since 
Example Question #161 : Integer Operations
Solve.
When a plus and minus are together, the sign changes to negative. When adding two negative numbers, we treat as addition but keep the minus sign in the end. The answer is 
Example Question #162 : Integer Operations
Simplify the following expression:
To solve this question you need to simply across. Performing the function that is is asking for. So,
Example Question #163 : Integer Operations
Both numbers are positive. Just add normally. The sum is 
Example Question #164 : Integer Operations
The plus and minus sign become a minus sign. It's just a subtraction problem. Answer is 
Example Question #165 : Integer Operations
Since 
Example Question #166 : Integer Operations
Since 
Example Question #167 : Integer Operations
When adding with another negative number, just treat as an addition problem and then add a negative sign in front. Our answer is 
Example Question #168 : Integer Operations
When adding with another negative number, just treat as an addition problem and then add a negative sign in front. Answer is 
Example Question #170 : Real Numbers
Add the following two integers:
We can look at the number line to help us understand adding integers. If we start at zero and move 3 integers to the left (negative) we will be at -3.
Now we will add 5 to this. We will move over to the right (positive) 5 integers.
And we end up at 2, which is the answer. We are adding both numbers but one of them happens to be a negative number. Because of the communtative property of addition it is possible to start with 5 and add -3.
and we still end up at 2.
