LarissaMath vs Geometric Sequence

LarissaMath helps memorizing basic mathematical operations. It will also help to speed up solving linear, quadratic, and cubic equations with an unknown variable. The Memory part comes from the Nobel Prize Winner in Economics Daniel Kahneman. He described the exercises in this app in his bestseller "Thinking, Fast and Slow". It has three modes: 1. Expressions. In easy level you need to calculate multiplication, division, summation, and subtraction where at least two arguments are no greater than 10. Some examples are: 5x3=15, 25:5=5, etc. The medium level also has calculations, but now at least two arguments are no greater than 25. Some examples are: 13x13=169, 225:15=15, etc. The advanced level has more advanced expressions using numbers up to 30. 2. Equations. In easy level you have to solve a linear equation on x. For, example, -2x + 15 = 11 (solution: x = 2). This equation should ideally be solved without pen and paper. Other equations in this level are fractions, e.g. x/10 = 9/6 or 4/x = 20/5, etc. The medium level has quadratic equations and the advanced level has cubic equations. 3. Memory. Here you can see a number with between 4 and 7 digits (depending on the level) and between 0.7 and 4 seconds (this is configurable in settings). The default time is 2 seconds, as suggested by Kahneman. You have to memorize it and then type a new number, having each digit increased by one. Nine gets converted to zero. For example, if the original number is 720983, the answer will be 831094. Additionally, the app remembers your best score and time for each mode, level, and for each number of entries.

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.
