    Read, analyze and reflect on these NOTES.

    1. When evaluating mathematical expressions, always be guided by the order of operations:

    a. Simplify all operations inside parenthesis.

    b. Simplify all exponents

    c. Perform all multiplications and divisions, working from left to right.d. Perform all additions and subtractions, working from left to right.

    Remember the mnemonic P-E-M-D-A-S ( Parenthesis-Exponents- Multiplications/Divisions-

    Subtractions-Additions).

    2. Numbers may be classified as prime, composite and natural denominate:

    a. Aprime numbersis a positive numberwhich may only divided by 1or itself.

    b. A composite numberis a positive number which has a positive divisor other 1 or itself. All

    even numbers are composite exceptthe number 2.

    c. A natural numberlike 0 or 1 is neither prime nor composite.

    d. A denominate numberis a number with an attached unit of measurement.

    3. Prime factorization is the process of finding which prime numbers tou need to multiply together to

    get the original number. There are 2 methods of Prime factorization.

    a. In the factor treemethod, we use a pictorial method of finding factors, where the

    number to be factorized is placed at the top and all its factors branch out one by one

    till we get all prime factors, just like a tree.

    factors as divisor until the last dividend becomes 1.

    4. The least common multiple (LCM) is the smalles multiple that 2 numbers have in common. The

    greatest common factor (GCF) is the larges multiple that can exactly divide 2 numbers. To obtain the

    LCM or the GCF, prform prime factorization of the 2 numbers and compare their prime factors.

    a. For LCM, after you list down the 2 factors, mark similar prime factors as one pair. After you have

    done so, multiply together the pairedand unpaired prime factors.

    b. For GCF, after you list down the prime factors, mark similar prime factors as one pair. After you

    have done so, multiply together the paired prime factors ONLY.

    1. Please be guided by the divisibility rules.

    Divisor Divisibility condition Examples

    2 The last digit is even (0, 2, 4, 6, or 8). 1294: 4 is even.

    3 Sum of the digits is clearly divisible by 3. 405 => 4 + 0 + 5 = 94 The last two digits are divisible by 4. 40832: 32 is divisible by 4.

    5 Thelast digit is 0 or 5. 495: the last digit is 5.6 It is divisible by 2 or by 3.

    by 3 and the last digit is even, hence the1,458: 1 + 4 + 5 + 8 = 18, so it is divisiblenumber is divided by 6.

    Subtracttwo times the last digit from the rest.The result should be divisible by 7

    483: 48(3 2) = 42: 42 is divisible by 7.

    8 The last three digits are divisible by 8. 34152: 152 is divisible by 8.Ad four times the hundreds digit to twice the tensdigit to the ones digit. The result should be divisibleby 8.

    34152: (4 1) + (2 5) + 2 = 16

    9 Sum of the digits is divisible by 9. 2,880: 2 + 8 + 8 + 0 = 1810 The last digit 0. 130: the las digit is 0.

    2. Recall the concepts of ratio and proportion.

    a.A ratio is an expression of the relative size of two quantities; it is usually expressed as the quotien

    of one number divided by the other. The ratio of 1 to 2 is written as 1:2 or 1/2.

    b.Aproportion is a statement of equality between two ratios. The ratio of 1:2 to 3:6 forms of the

    proportion 1:2 = 3:6 or = 3/6.

    3. Recall the concept of percentage, base and rate.a. Thepercentage is the fraction of the original number that is obtained by multiplying the rate and th

    base. In problems, it is the number that comes before the word is.b. The baseis the number or quantity which represents the original number. It also represents the tota

    It is obtained by dividing the percentage by the rate. In problems, , it is the number that comes afterthe word of.

    c. The rate is the number represents the percent. It is obtained by dividing the percentage by the base.In problems, is the number that is attached to the word percent or to a % sign.

    d. To facilitate recall of the formulate for percentage, base and rate, draw a PBR triangle.
