Associative Property :. When adding multiple numbers together, the outcome sum is the same regardless of the order the numbers are placed in. Unlike addition, the order of two numbers in subtraction changes all the results. In other words, the subtrahend and minuend are distinct factors when subtracting and they cannot be switched order-wise except subtrahend and minuend are equal.
When subtracting multiple numbers, the order of the numbers does matter. Subtracting numbers in different orders will result in different outcomes. When multiplying two numbers together, the product is the same regardless of the order the numbers are placed in.
When multiplying multiple numbers together, the product is the same regardless of the order the numbers are placed in. Property of Zero :. Property of One :.
Identity Property of One :. In each case, the answer is positive. Step 1 : Parentheses — Simplify any expressions inside parentheses. Step 2 : Exponents Powers, Roots — Work out any exponents. Step 3 : Multiply or Divide before you Add or Subtract. Step 4 : Addition and Subtraction These are done last, working from left to right. Fractions are another way to express division. The top number of a fraction is called the numerator, and the bottom number is called the denominator.
The LCM of a set of numbers is the smallest number that is a multiple of all the given numbers. For example, the LCM of 5 and 6 is 30, since 5 and 6 have no factors in common. The GCF of a set of numbers is the largest number that can be evenly divided into each of the given numbers.
For example, the GCF of 24 and 27 is 3, since both 24 and 27 are divisible by 3, but they are not both divisible by any numbers larger than 3. Fractions must have the same denominator before they can be added or subtracted. If the fractions have different denominators, rewrite them as equivalent fractions with a common denominator. Then add or subtract the numerators, keeping the denominators the same.
For example :. When multiplying and dividing fractions, a common denominator is not needed. Our site only allows each person to take each test only one time. You have to finish the following test before beginning this one:. You answered 0 out of 0 questions correctly, 0. How long is the Arithmetic Reasoning test?
A few sites worth looking into if you need help with the concepts are mathportal. The following arithmetic concepts are likely to be included within your question set, understanding how they are calculated and practical applications of these will be necessary to score well:.
If you are show up late, you will not be allowed to take the test at that time and will be required to reschedule for another time. The test is administered through a computer most commonly, with a few exceptions at various MET sites. Everything you will need to complete the test is provided for you. Therefore, you are not allowed to bring in any personal items to the testing center.
This includes a calculator and any electronic devices. The test as a whole is made up of 10 subtests with a total of scored questions.
However, each test is allowed to have two to four subtests or sections that contain as many as 15 pre-test or tryout questions included. If these tryout questions are present, they will be scattered throughout the section and extra time will be given for completion. Unlike with the paper and pencil form of the exam, the computer administered test or CAT allows each individual to take the test at their own pace.
When you finish a subtest, you can immediately begin to take the next subtest. The CAT is given, on average, two hours to finish, depending on whether or not tryout questions are present. The Arithmetic Reasoning subtest falls into the math domain.
