Example Questions
Example Question #11 : Operations
What expression is equivalent to:
First, add the numbers in parentheses.
Now put the equation together.
Example Question #12 : Operations
What expression is equal to 24?
Remember the order of operations with the help of the acronym PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Only one of the expressions in the answer choices which will give us the quantity we are looking for.
Example Question #13 : Operations
If , what number does
stand for?
11
6
8
3
8
There are two ways to solve this question: one is to try each answer in the place of , and another is to solve it with algebra.
To solve algebraically, first, divide both sides by 2:
Subtract 3 from both sides:
Example Question #14 : How To Multiply
__ ?
There is a quick shortcut that you may notice in this problem (and problems like it) that will keep you from having to doing a lot of large computations. As you look at the left side of the equation, notice that you can factor out a from the
, which gives you a
on the left:
__ ?
__?
Now we can divide each side by , which leaves us with:
, which equals
, which equals
Example Question #15 : How To Multiply
Which of the following is a valid approximation of the problem:
Round each of the numbers:
Multiply:
35 is a valid approximation for the problem. The precise answer is:
Example Question #14 : Operations
Evaluate:
The expression is undefined.
A negative number taken to an odd-numbered power is negative, so:
Example Question #182 : Numbers And Operations
Evaluate:
By order of operations, exponentiate first, then add:
Example Question #183 : Numbers And Operations
Solve for :
Example Question #184 : Numbers And Operations
Mulitply:
We ignore the decimals for the time being, multiplying:
Since, between them, the two original factors have a total of three digits to the right of their decimal points, we place the decimal point in the product so that there are three digits to the right. This yields:
