The Mathematics subtest of the UPCAT (UP College Admission Test) contains questions from different topics you learned in high school. Although UPCAT questionnaires vary every year, Math questions will most likely come from the following subtopics:

a. Arithmetic and Number Sense.

b. Algebra.

• Signed Numbers
• Algebraic Expressions
• Equations and Inequalities
• Systems of Equation
• Polynomials
• Functions and Relations
• Fractions and Rational Functions
• Cartesian Coordinate System (Graphing)
• Word Problems
• Exponents and Logarithms
• Sets and Set Notation
• Complex Numbers
• Sequences and Series

c. Geometry.

• Reasoning
• Definitions, Postulates, and Theorems
• Angles
• Parallel and Perpendicular Lines
• Triangle Postulates and Theorems (ASA, SSS, etc.)
• Area and Volume
• Circles

d. Trigonometry.

• Basic Trigonometric Functions
• Basic Identities

e. Statistics.

• Measures of Central Tendencies (mean, median, mode)
• Factorials
• Counting, Permutation, and Combination
• Probability

#### UPCAT Math Review Tips and Tricks.

• Focus on the basics. Advanced math topics like calculus are nice to learn but don’t expect them to appear in the UPCAT. Students with a good grasp of the fundamental math formulas and principles can handle even the most complex math problems.
• Trigonometry questions may appear but in only a few items. Review trigonometric ratios and basic applications.
• Since calculators will not be allowed on the day of the exam, make sure you know how to compute by hand or through mental math techniques. Brush up on the multiplication table. Practice solving long division problems. You can also download a PDF copy of Speed Math for Kids if you’re still struggling with basic calculations.
• Supplement your math review with free YouTube tutorials. Channels like PatrickJMT provide clear, easy-to-follow math lessons you might have missed in school.
• Master solving math problems involving fractions. Learn how to do the four basic operations on similar and dissimilar fractions as well as how to express your answers in lowest terms.
• Answer as many practice tests as possible. You may not be able to cover every single math topic on your review but you’ll develop problem-solving skills that are essential in passing UPCAT. Besides, you can remember math formulas better with repeated testing/application than with rote memorization.
• When reviewing for UPCAT, internalize, don’t memorize.  Understand the math behind every formula. If you just memorize math formulas, you’ll fall victim to formula blindness, a phenomenon wherein students fail to solve a problem because they assume the question is asking for a specific formula when in fact it requires something else. To prevent this, review how math formulas are derived so you won’t be misled to use a formula in a problem that deceptively asks for another similar formula.
• Familiarize yourself with the Filipino translations of common math terms, shapes, and measuring units (see table below). Questions in Filipino may appear in all subtests not just in Language Proficiency and Reading Comprehension.

Directions: The Mathematics subtest will test your ability to solve quantitative problems quickly and accurately. Analyze each problem and select the best answer from the multiple choices.

The practice tests are organized around five fundamental math concepts that will be included in the actual UPCAT: arithmetic and number sense, algebra, geometry, trigonometry, and statistics.

To mimic the actual test conditions, you’re not allowed to use calculators. Because UPCAT is a time-pressured exam, we also recommend using a timer when taking the practice test.

Begin by setting up an equation representing the average. (2 + x + 31) ÷ 7 = 24. Solve for x to find 135 and recognize that this x represents the sum of the remaining 5 scores. To find the average, divide 135 by 5 to find 27.

If a triangle has side lengths a, b, and c, the sum of the lengths of any 2 sides must be larger than the length of the 3rd side. So in this case, 5 + 6 = 11 must be larger than side length c. From the answer choices, 12 is the only length greater than 11, so it cannot be the length of the third side.

Recall that vertex- form of a parabola is:

a(x − h)2 + k, where (h, k) represents the vertex.

We wish to translate our vertex from (0,0) to (4,−6) so h = 4 and k = −6.

ƒ(x) = (x − 4)2 – 6

Recall that slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Solve for y:

8x − 2y = −6

2y = 8x + 6

Divide everything by 2:

y = 4x + 3

The circumference of a circle is the distance around defined by π * diameter. The diameter, in this case, can be found through the difference between the x values:

3 − (−3) = 6, so π * 6 is the circumference.

| 2(x – 1) – 15 | = 7

| 2x – 2 – 15 | = 7

| 2x – 17 | = 7

2x – 17 = – 7  and 2x – 17 = 7

2x = 10 and 2x = 24

x = 5 and x = 12

The solution set: { 5,12 }

If the product of two numbers is positive, the two numbers must have the same sign. That is, if ab > 0, then either a > 0 and b > 0, or a < 0 and b < 0.

We are told that A < −1 (which implies that A < 0).

So we know that B < 0.

We also know that AB = 1, so A = 1/B

Since A = 1/B, and A < -1, we can infer that 1/B < -1

If we take reciprocals on both sides of the last inequality, we must flip the inequality sign. Hence: B > −1

So we know that B < 0, and B > −1. We can represent this as a compound inequality: −1 < B < 0

For this question, you have to examine all the answer options individually in order to eliminate all those that cannot be true. First, if x is positive and y is negative, their product must be negative, so (A) is incorrect.

Next, the sum of a positive and a negative number could be either positive or negative, depending on which number has the greater absolute value; this rules out (B) because it’s not always true.

Similar reasoning applies to choice (D) as well. However, both positive and negative real numbers have positive squares, and adding those positive squares will always yield a positive number, so (C) is correct.

Because both of these equations are already solved for the variable x, we can set them equal to each other to find the value of y. Begin by multiplying both sides by 3 to remove the denominator.

y − 7 = y + 4

Notice that this equation will never be true. Since there is no solution, so we can conclude that the lines do not intersect.

Recall the slope-intercept form of a line:

y = mx + b where m is the slope.

Solve the given equation for y to find the slope:

2x − 6 − 6y = 10

−6y = −2x + 16

y = 1/3x − 16/6

Slope is equal to 1/3.

She runs for 20 minutes and arrived 5 minutes late → She needs to be exactly there in 15 minutes.

Using a bike with a speed of 1/3 km per minutes → t = d/r → t = 2/1/3 → t = 6

15 minutes – 6 minutes = 9 minutes earlier.

From the chart, we can see that Store X had 80 (thousand) in profits and Store Z had 100 (thousand) in profits. Combining these two, we arrive at 180 (thousand) in profits.

A square is a rhombus and a rectangle. Therefore, some rhombuses are rectangles.

Problems involving similar figures can be solved using proportions. The issue with this problem is that we are given a similarity across inches to feet with the answer choices containing only inches. First, we must convert the feet measurement into inches:

2 1/3 ft. x 12 in./ft. = 28 in.

We can now set up our proportions:

4/7 = x/28

x = 16

Solve the inequality for one variable:

y + 3 > −3x + 6

y > −3x + 3

This states that the y-coordinate must be larger than −3 times the x-coordinate plus 3. Test the points provided to see which one satisfies the given inequality (this can also be done graphically). Only (−3, 15) satisfies the inequality.

We solve this problem by replacing every x in h(x) with 2x − 3 and evaluating the expression:

h(2x − 3) = 3(2x − 3) + 4

= 6x − 9 + 4

= 6x − 5

Let a = -0.9 and b = -0.1

A. b – a = (-0.1) – (- 0.9) = 0.8

B. a + b = (-0.1) + (-0.9) = -1.0

C. a – b = (-0.9) – (-0.1) = -0.8

D. 2b – a = 2(-0.1) – (-0.9) = 0.7
