P.E.M.D.A.S. is an acronym that represents the order of operations in math problems: (1) Parentheses, (2) Exponents, (3) Multiplication and Division from left to right, (4) Addition and Subtraction from left to right. You always complete the operations in each step before moving to the next. For example, any calculations in parentheses are performed first, followed by exponents, then multiplication/division, and finally addition/subtraction.

Friedman's test is a nonparametric test used to detect differences in treatments across multiple test blocks when using ordinal or ranked data. It involves ranking the data within each block, summing the ranks for each treatment, and calculating a Friedman test statistic that is compared to a chi-square critical value to determine if the null hypothesis that the treatments have identical effects can be rejected. An example demonstrates constructing a table with ranked data, calculating the Friedman statistic, determining the degrees of freedom, looking up the critical value, and comparing it to the statistic to evaluate the null hypothesis. The test can also be performed in Excel using the Analyse-it plugin.Primefactorization

Prime factorization is writing a number as a product of prime numbers. To perform prime factorization, you first make a factor tree by finding all the factors of a number and continuing to break down factors until only prime numbers remain. The prime factors are then written as a multiplication expression, with exponents used if any prime numbers are repeated. Prime factorization can be used to find the lowest common multiple of two numbers by identifying common prime factors between their factorizations.What is the pairwise comparison method

Pairwise comparison is a decision-making method that visually compares all potential options to each other to determine the best option. It involves creating a table with the options in rows and columns and comparing each option pairwise to rate their relative importance. The ratings are totaled and can be converted to percentages to clearly show the preferred option. An example uses three potential CRM systems as options to demonstrate how the method works step-by-step to compare and score the options to reveal that a renowned CRM system is the clear winner. While a useful tool, the pairwise comparison results should not be the sole basis for decision-making.Order Of Operations

The document discusses adding and subtracting fractions with like denominators. It explains that fractions have like denominators if they have the same number on the bottom. To add fractions with like denominators, you add the top numbers and keep the bottom number the same. To subtract fractions with like denominators, you follow the same steps as addition but subtract the top numbers instead of adding them. Examples are provided to demonstrate both addition and subtraction of fractions with like denominators.Math Order odf Operations

- 2. Parenthesis Parenthesis is the first thing you do in a math problem. This is an example of parenthesis: (4+3) Always do what is in the parenthesis first, no matter what
- 3. Exponents Exponents is the second thing you do in a math problem An example of an exponent is: 3 2 (The exponent is in orange) Always do exponents first unless there are any other operations in parenthesis
- 4. Multiplication and Division The next step is to do the multiplication and division from left to right Always do any multiplication or division after you have completed all exponents and any work in parenthesis An example of this would be: 3 x 4 or 12/4
- 5. Addition and Subtration This is the final step in P.E.M.D.A.S. Always do any addition or subtraction from left to right Always complete this step last unless there is and addition or subtraction in parenthesis An example of this is: 5+4 or 9-6
- 6. P.E.M.D.A.S. An example of all the orders of operations would be: (3+4) x 2 3 - 8 = ??? The answer is 36!
