About Arsenio

Hello. I have been tutoring students for the past 5 years. I graduated high school with my Advanced Regents Diploma. I received a 92 on my Mathematics A Regents and an 85 on my Mathematics B Regents. My high school transcript states my Mathematics "Subject Area Average" from ninth to twelfth grade as 95.33%.

Every student is different. Some students grasp quickly while others might take a little longer to grasp depending on the subject area. No matter the case, you (the student or parent) will never be looked down upon. Remember that I was once in your shoes. Therefore, I can quickly draw back on my previous learning experiences to make you a better student.

Through WyzAnt, I have been fortunate to tutor students of various backgrounds and skill sets in Mathematics. I have tutored students as young as 5 years old to students old enough to be my parents. Past students have described me as a tutor who "breaks down complex math problems and makes it simple (with step by step explanation) that his student's will understand." Check my status and see that my average rating given by my students is 4.8 out of 5. Out of 137 ratings, I have received one hundred fourteen 5 STAR Ratings!

Do not hesitate to contact me. You will not be disappointed!

Hey Monica. I could tell you were brilliant from the start. I look forward to continuing with you and having you flourish. Be well!

"Personable & Patient"

- Cheryl, Brooklyn, NY on 11/19/15
Arsenio replied on 11/25/2015

Your son is very intelligent. So far, after two lessons, I notice he grasps quickly and flows smoothly once he sees that he can apply the knowledge. I'm interested to see his progression as time goes on.

"great tutor"

- TESSA, New York, NY on 7/17/15
Arsenio replied on 7/22/2015

Thank you. You are very intelligent... One point about your review: The ease doesn't begin once you understand it 100%. Once you begin understanding the work, it just gets easier. Hope you understand what I mean by that... Stay consistent with your effort and we will both continue to see your improvement.

"Very patient and knowledgeable. Easy to work with."

Arsenio replied on 7/8/2015

Your daughter is very smart. I see her confidence grow with every lesson. As long as your daughter stays dedicated, she will continue to show improvement. I look forward to seeing how her confidence increases as we move along. So far, she is doing a great job.

"Very patient. Great work ethic."

- Andrea, Brooklyn, NY on 2/6/15
Arsenio replied on 2/10/2015

- Nancy, Brooklyn, NY on 7/31/14
Arsenio replied on 8/1/2014

Thank you! Your daughter's willingness to get better showed from the very first session. That made me very eager to teach her. She should be very proud of her improvements, especially in such a short amount of time.

"Well Mannered, Bright Young Man"

- Albert, Brooklyn, NY on 6/9/14
Arsenio replied on 6/10/2014

Thank you. I definitely did not expect this. Your son is also very bright. I have no doubt about his ability to learn and perform the math at a high level. I will do my best to have him ready for the upcoming Regents Exam. Thank you once again.

"Hire Arsenio"

- Allison, Brooklyn, NY on 12/9/13

- Swen, Brooklyn, NY on 6/10/12
Arsenio replied on 6/15/2012

Thank you. I always respected what you represent as a man. Most importantly, I always respected your humility and honesty. Many men don't have the humility to allow someone younger to tutor them. I always appreciated that from you. Thank you once again.

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Algebra 1

Inequalities- involve >,<,>=,<=

Factoring- Find GCF and divide each term in the expression by the GCF

Factoring Radicals- the square root of the product is equivalent to the square root of its factors

Order of Operations
PEMDAS (Parenthesis Exponent Multiplication Division Addition Subtraction)

Number Theory
Real Numbers- All numbers from negative infinity to infinity
Rational Numbers- Numbers that can be written as a ratio
Irrational Numbers- Numbers that cannot be written as a ratio.

Perimeter of Polygon = Sum of all the sides
Area of parallelogram = Length* Width
Volume of object= Area* Height

Solving an Equation for an unknown, usually 'x'.

Solving a System of Equations
Elimination Method = When adding two equations, get rid of one of the variables while solving for the other. After finding the value of that variable, substitute it in one of the original equations to find the value of the eliminated variable.

Substitution Method- Solve for one variable in terms of the other. Substitute that variable into one of the original equations. Solve for the remaining variable. Substitute that value into one of the original equations to find the value of the other variable.

Setting the Equations Equal to Each Other Method- Solve each equation so they both equal the same thing, i.e 'y' or 'x'. You can now set the equations equal to each other. Follow the method for substitution.

Algebra 2

Numbers and operations: understanding fractions and decimals, arithmetic mean, properties of exponents and radicals, prime and composite numbers

Algebra and functions: solving equations and inequalities, understanding the properties of functions, testing for functions, inverse functions

Geometry and measurement: understanding shapes and using their properties to accurately solve problems, understanding acute, obtuse, and right angles, parabola, circles

Data analysis, statistics, and probability: reading and interpreting graphs, arithmetic mean, sample space, experiment, observations, survey.


Tutoring will cover the following topics of geometry:

Laws Of Transversals
Corresponding Angles are congruent.
Alternate Interior Angles are congruent.
Alternate Exterior Angles are congruent.
Vertical Angles are Congruent.

Triangles: The sum of all three angles is 180 degrees. Equilateral Triangles: All 3 sides have same measure. All 3 angles have same measure.
Isosceles Triangles: 2 sides have same measure. 2 corresponding angles have same measure
Scalene Triangles: All 3 sides and all 3 angles have different measures.

Quadrilateral: any object with four sides
Parallelograms: a quadrilateral with two pairs of parallel sides. Has 2 congruent sides
Rhombus: A parallelogram with 4 congruent sides
Rectangle. A parallelogram which forms 4 right angles.
Square: A Rectangle with all sides congruent

Trapezoid: Has one pair of parallel sides.
Isosceles Trapezoid: Has two congruent sides.

Proofs of Congruency
SAS: (Side-Angle-Side); A triangle is congruent to another triangle if they share two congruent sides and a congruent angle.
ASA:(Angle-Side-Angle); A triangle is congruent to another triangle if they share two congruent angles and a congruent side
SSS:(Side-Side-Side); A triangle is congruent to another if they share 3 congruent sids

AAA: Angle-Angle-Angle; A triangle is NOT CONGRUENT but SIMILAR to another triangle if they share 3 congruent angles

CPCTC: (Corresponding Parts of Congruent Triangles are Congruent) If two triangles are congruent, then each part of one triangle is congruent to the corresponding part of the other triangle.


Trigonometry is the knowledge of triangles.

Basic Concepts;
Sum of Angles of a Triangle= 180 degrees

Sin= opposite/hypotenuse
Cosine= adjacent/hypotenuse
Tangent= opposite/adjacent

secant= 1/cosine
cosecant= 1/sine
cotangent= 1/tangent

Pythagorean Theorem
a^2+b^2=c^2, where "c" is always the hypotenuse and "a" and "b" can represent either leg.

Patient & Knowledgable — I met Arsenio this weekend, as I'm an adult returning to school after raising a family. Math has never been my strong suit, Algebra in this case, so I'm trying to give myself an advantage and brush the cob webs off my brain. I feel confident with Arsenio's assistance I'll pass my class and the Final Exam. ...
