Find the product of 84 and 76.
To find the product, we will multiply the two numbers together. We get
Multiply, starting from the right. We get 24. We write the 4 and we carry the 2.
We multiply the red numbers, and we get 48. We add the blue number to get 50.
Multiply the red numbers, and we get 28. We write the 8 and carry the 2.
We multiply the red number. We get 56. We add the blue number, and we get 58.
Now, we add them together.
We add the red numbers. We get 4.
We add the red numbers, we get 8.
We add the red numbers. We get 13. We write the 3 and carry the 1.
We add the red numbers. We get 6.

and
so your answer is
Example Question #82 : How To Multiply
Solve for 
This problem involves following the order of operations.
First we multiply.
So, we are left with
Then we just solve from left to right, meaning
Example Question #83 : How To Multiply
Solve for 
There is not enough information to solve this problem.
This problem involves using order of operations.
Therefore, we must do what is inside the parentheses first.
So, then we have
Then, we would multiply and be left with
Then, you just add from left to right and we are left with

20 ÷ 8 =
2 remainder 4.
17 ÷ 8 =
2 remainder 1.
18 ÷ 8 =
2 remainder 2.
12 ÷ 8 =
1 remainder 4.
Example Question #82 : Operations
Find the quotient, when 
Example Question #83 : Operations
Solve the expression.
We can re-write the expression using division.
We need to use order of operations to solve. First, evaluate the parenthesis.
In the first parenthesis, we need to multiply before we add.
Finally, we can divide. Remember that a positive divided by a negative is a negative.
