MULTIPLICATION AND DIVISION OF INTEGERS (A) Multiplying integers
1. The product of multiplication between two integers with the same sign is positive. If two integers have different signs, the product of the multiplication is negative.
2.
If zero is multiplied by any integer, the product
is always zero.
(B) Solving problems involving multiplication of integers
(C) Dividing integer 1. The quotient of division between two integers with the same sign is positive. If two integers have different signs, then the quotient of the division is negative.
2.
If zero divided by any integer (except zero), the quotient
is zero. 0 ÷ 10 = 0 3. Any integer divided by zero is undefined.For example: 6 ÷ 0 = undefined
(D) Solving problems involving division of integers
(A) Performing computations involving combined operations on integers 1. Combined operations involve more than one operation on integers are also known as mixed operations. 2. For combined operations involving' + ' and '  ' or ' x ' and ' ÷ ', work the calculations from left to right following the order given. (B) Solving problems involving combined operations on integers POSITIVE AND
NEGATIVE FRACTIONS (A) Comparing and ordering fractions
(B)
Computations Involving Addition, Subtraction, Multiplication and
The same rule used for adding and subtracting integers is used in the addition and subtraction of positive and negative fractions. Multiplication of positive and negative fractions is similar to the multiplication of integers. POSITIVE AND NEGATIVE DECIMALS (A) Comparing and ordering decimals
(B) Adding and Subtracting Decimals The same rule used in adding and subtracting integers is used in the addition and subtraction of positive decimal.
(C) Multiplying and Dividing Decimals The same rule used in multiplying and dividing integers is used in the multiplication and division of positive and negative decimals.COMPUTATIONS INVOLVING DIRECTED NUMBERS (A) Addition, Subtraction,
Multiplication and Division Involving Two
Calculations involving two directed numbers with any operations are the same as that for integers, fractions and decimals.
(B)
Combined Operations of Addition, Subtration, Multiplication
and For computations involving the use of brackets and combined operations of addition, subtraction, multiplication and division on positive and negative numbers, calculate according to the following order. 1. The brackets ( ) 2. 'of' (which means x) 3. ÷ and  (from left to right) 4. + and  (from left to right)
(C)
Combined Operations of Addition, Subtraction,
Multiplication and
(d) Combined Operations on Positive and Negative Decimals
(e) Combined Operations on Directed Numbers
(f) Solving Problems Involving Directed Numbers
