Example Questions
Example Question #21 : Operations
Which expression is equal to 24?
Remember the order of operations, so work inside parentheses first:
Then everything else:
Example Question #22 : Operations
What is the product of 
The term "product" indicates multiplication.
Example Question #23 : Operations
Which expression is equal to 
One should use order of operations (PEMDAS) to solve this equation. In the equation 
Multiplication is next in this equation, according to order of operations:
Subtraction comes last:
Example Question #23 : Operations
What is the product of 
A product is the result of a multiplication problem.
Therefore, the product of 
Example Question #24 : Operations
Yesterday, Joe's dad worked for 7.5 hours at a rate of $12.50 per hour. Approximately how much money did he earn yesterday?
$166
$95
$60
$125
$75
$95
First look at the answer choices. They are all at least $15 apart from one another, so we know that we can approximate the answer without worrying about being off by $1 or so.
Let's round 7.5 hours up to 8 hours, and then $12.50 down to $12. Working 8 hours at a rate of $12 per hour gives us a total earnings of $96. The closest answer choice is $95, so that's our answer.
The exact total is in fact $93.75, which is very close to both the answer choice and our approximation.
Example Question #25 : Operations
Find the product. Round to the nearest tenths place.
Multiply 
After finding the product, don't forget to move the decimal in FOUR places because each number has 2 decimal places 
The product is 
Then, round to the nearest tenths place 
Example Question #26 : Operations
What is a reasonable estimate for
First, estimate each number. 2.3 rounds to about 2, while 3.1 rounds to about 3. Then, mulitply 2 and 3.
Example Question #27 : Operations
How many millimeters are in 6 meters?
There are 1,000 mm in each meter. Therefore, you must multiply 6 by 1,000 to get 6,000 millimeters.
Example Question #27 : How To Multiply
A wooden board is 
There are 
To simplify the multiplication, you can break up the decimal:
Example Question #193 : Isee Lower Level (Grades 5 6) Mathematics Achievement
What is the square root of 144?
The square root operation is the inverse of a number raised to the second power. In other words, we are looking for the number that, when squared, equals 144.
When the number 12 is multiplied by itself, the product is 144.
Therefore, 12 is the correct answer.
