The Cartesian Coordinate Plane vs Mathy

The DOST Courseware is a locally-produced, all-original Filipino highly interactive multimedia educational application packages that are conceptualized, digitized and produced as spearheaded by the Science Education Institute (SEI-DOST) in partnership with the Advanced Science and Technology Institute (ASTI-DOST) and in cooperation with the Department of Education (DepEd), Philippine Normal University (PNU) and University of the Philippines-National Institute for Science and Mathematics Education (UP-NISMED), which aims to develop information and communication technology learning innovation to support the upgrading and improvement of science and mathematics education in the country. The DOST Courseware are provided for free to schools and are also made available online as supplemental resources for teachers and student as a fun and interactive approach to e-learning and blended learning. The Grade 7 DOST Courseware is composed of 120 lessons overall, 73 lessons in Science where it covered the domains on: Matter; Force, Motion and Energy, Living Things and Their Environment and Earth and Space while the 60 lessons in Mathematic covered the domains on: Numbers and Number Sense, Patterns and Algebra, and Geometry. The Grade 8 DOST Courseware is composed of 118 lessons overall, 61 lessons in Science where it covered the domains on: Parts and Functions, Ecosystems, Heredity: Inheritance and Variation of Traits, Structures and Functions, Biodiversity, and Evolution, while the 57 lessons in Mathematics covered the domains on: Linear Equations, Quadratic Equations, Rational Algebraic Equations, Integral Exponents, Radicals, Arithmetic Sequence and Geometric Sequence. The themes of the courseware for Grades 7 and 8, Magicademy, Freddy’s Lab and D’nayao will surely amuse the users as they explore these distinct worlds while learning at the same time.

Train your mental math for case interviews, school, or just for the fun of getting faster. Mathy is a fast, focused mental math trainer built for the numbers that show up when speed matters: consulting case interviews, exams, homework, business estimates, and everyday brain training. Whether you’re preparing for consulting or finance case interviews, class, or your own personal best, Mathy helps you turn tricky calculations into reflexes. Practice big round numbers, percentages, market-share math, clean division, fraction simplification, and zero-tracking until they feel natural. Work through drills across: - Addition and subtraction, from warm-ups to large-scale numbers - Multiplication with clean, practical values - Division with answers that land cleanly - Percentages, including percent-of-a-number, percent-of-a-percent, and reverse percentage problems - Market-share style calculations - Fraction simplification Choose the practice mode that fits your moment: - Timed Round to build speed under pressure - Fixed Set of 10, 20, or 50 questions for deliberate practice - Endless Mode for warm-ups, flow, or long training sessions Set your difficulty level, or let Mathy surprise you with a random level. Keep it light, make it serious, or push yourself until your brain starts seeing patterns automatically. After every session, Mathy shows a clean results table with your answer, the correct answer, and how long each question took. You’ll see where you’re improving, where you’re slowing down, and when you beat your personal best. Tap any question to see how Mathy would solve it: a clear, step-by-step mental-math strategy that breaks the problem into the rounding, multiplying, and adjusting a fast solver would actually do in their head. It's not just the right answer; it's the shortcuts to get there. Mathy is fully offline, private, and built for speed. No accounts. No tracking. No data leaving your phone. Just instant feedback, zero lag between questions, and a native iOS experience that gets out of your way. For interviews, school, or the simple satisfaction of sharper mental math: open Mathy and start drilling!
