Integers
1. When both integers have the same signs keep the sign and add. When the signs are different, disregard the signs, subtract the numbers, and keep the sign of the larger number.
2. Change the sign of the number being subtracted. Then add using the preceding rules.
3. Multiply as you would whole numbers. The product is positive if there are an even number of negative factors. The product is negative if there are an odd number of negative factors.
4. Forget the signs and divide. The quotient is positive if both integers have the same sign. The quotient is negative if the integers have different signs.
Formulas
Using a formula is like evaluating an expression. Just replace the variables with values. Here are some important formulas to know. The area of a figure if the amount of space it occupies in two dimensions. The perimeter of a figure is the distance around the figure. Use 3.14 for , b —- base, h — height, s — side, l — length, w — width, r — radius, d — diameter.

Equations
The whole idea of solving equations is to isolate the variable on one side of the equal sign. The value of the variable is what’s on the other side of the equal sign. Substitute your answer into the original equation to check your solution. Solving two-step equations add or subtract before you multiply or divide: 3x – 6 = 24.
READING AND INTERPRETING GRAPHS
Examples of the four main types of graphs are shown below. The Pictograph uses symbols to stand for numbers. The Bar Graph represents information by the length of a bar. The graph below shows the rainfall during two months in each of five towns. The Line Graph plots information against two axes. The Circle Graph represents an entire amount. In the graph below, each wedge-shaped piece of the graph represents the percent of tax money spent on different town services.
POST-READING ACTIVITIES
Say what you’ve learned from the texts about:
1) the special strategies for answering the mathematics multiple-choice items;
2) the concepts and topics do you need to know to pass mathematics part of the LAST;
3) the review sections of the mathematics part of the LAST.
Vocabulary practice
Ex. 1. Make sure you understand and can explain the following terms and notions:
Mathematics, Algebra, Geometry, Statistics, Probability, problem, mode, mean, product, expression, operation, factor.
Ex. 2. Translate the LAST test objectives (SUBAREA I: 01-03) followed by focus statements that provide examples of the range, type, and level of content that may appear on the test (for a list of test objectives, see APPENDIX B).
Ex. 3. Complete the following sentences with the appropriate word.
1. … are used to represent numbers between 0 and 1.
2. Descriptive … are used to explain or describe a set of numbers.
3. … numbers such as 1st, 2nd, 9th, and 18th tell about order.
4. The … is the number that occurs most often.
5. The negative whole numbers and the positive whole numbers are called … .
Ex. 4. Select the term that seems odd.
1. sequence — equivalence — series — succession
2. common fraction — simple fraction — vulgar fraction — complex fraction
3. digit — number — decimal — numeral
4. median — medial — mode — middle
5. ratio — progression — fraction — proportion
Ex. 5. Supply the sentences with required words; if necessary change their grammatical forms.
perimeter variable volume square area formula
1. Using a … is like evaluating an expression.
2. Just replace the … with values.
3. The … of a figure if the amount of space it occupies in two dimensions.
4. The ... of a figure is the distance around the figure.
5. The … of a figure if the amount of space it occupies in three dimensions.
Ex. 6. Replace each italicized word or phrase with the correct word.
1. When both integers have the same signs keep the sign and subtract.
2. Write any mixed number as an proper fraction.
3. The events are dependent when the outcome of one event does not affect the probability of the other event.
4. The product is negative if there are an even number of negative factors.
5. The quotient is positive if both integers have the different sign.
