Systems of equations solver vs Direct Proportion

The calculator solves systems of linear equations with two and three variables. • System solver 2x2 Solves systems of two linear equations in two variables by substitution or using using Cramer's rule. • System solver 3x3 Solves systems of three linear equations in three variables using Cramer's Rule. To solve 3x3 systems of equations, you should select a landscape orientation. Features: Shows step-by-step solution. Supports integer, fractional and decimal coefficients. Shows results as decimals and fractions. Stores history with the possibility to recall previous equations. Sends results and history via email. Supports both portrait and landscape orientation.

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.
