This app for the digital SAT is unique in the world, provides you with everything you need to improve your Math score—guaranteed. 29 years of experience and a unique approach have led to the ultimate product that outdoes any other digital SAT prep book or application. There are 386 exercises as follows: Algebra: 120 exercises Problem Solving and Data Analysis: 108 exercises Advanced Math: 120 exercises Geometry and Trigonometry: 38 exercises Students can access all exercises of the app in a lot of ways: A: exercises & solutions - by chapter B: exercises & solutions - by category C: play & learn - by chapter D: play & learn - by category E: as a digital SAT TEST in 2 modules with 2x22 = 44 questions F: as a single TEST with 22 questions --> 386 practice questions with expert explanations in 32 chapters or 8 categories --> full theory with over than 300 examples --> Use of both multiple-choice and student-produced response question formats --> the only app with student - produced response exercises (grid-in) --> practice on each chapter separately - play & learn --> a different test for each student.The test questions are selected randomly from the 365 exercises, --> this app generates millions of different tests, --> you can save the test as a .pdf file --> Automatic pagination of the test into 5 - 20 pages --> millions of ****** printable ****** tests --> you can save the answers of the test as a .pdf file --> see the scores and subscores immediately --> save or print the scores as a .pdf file --> use the chronometer to control your test time --> each module last for 35 minute --> students get an alert when 5 minutes remain in the module --> digital SAT 2-module test with 2x22 = 44 questions (following the specifications of the digital SAT math test) --> Once time has expired for the first module, students are automatically advanced to the appropriate (higher- or lower-difficulty) second module and may not return to the questions in the first module. --> Each module is separately timed, and students can move backward and forward among questions in a given module before time runs out --> test with 22 questions ideally to be taught in a teaching hour. Try to finish it in 35 minutes --> you can see the solutions in portrait view or in landscape view ***** text books can not do all these ***** ***** the best, smartest and cheapest way to practice for the digital SAT math TEST ***** The application presents only my point of view for the whole syllabus. Exercises have emerged from twenty-nine years of experience in teaching of Mathematics. Visit our blog: http://i-math-apps.blogspot.com/ for more videos, questions, comments, suggestions e.t.c.

PEMDAS is an acronym that is taught in school classrooms across the nation. It helps students remember the priority, or Order of Operations, used to solve expressions involving strings of numbers and operators. It stands for: P(arenthesis) E(xponent) M(ultiplication) D(ivision) A(ddition) S(ubtraction) A familiar mnemonic widely used in place of PEMDAS is: Please Excuse My Dear Aunt Sally. Thus the name of this application... Kind of an inside joke for the mathematical types. Computers, including smart phone calculators, desktops, etc. have built in functionality to properly interpret such expressions so we don't have to. But have you ever wondered what algorithms the CPU executes to get the right answer every time? This app demonstrates one such algorithm called the Shunt Yard, developed a few years back by Professor Edsger W. Dijkstra. We’re going to take a closer look under the hood at Order of Operations algorithms. It will interest programmers and school students alike; for programmers, the use of queues and stacks will reinforce previous computer science learning; for students, it allows them to write an expression, then analyze it using Order of Operations rules, step by step. The Quiz mode generates random expressions of user selected lengths and magnitudes and checks the student's answer. Incorrect answers can be examined using the same step by step process. In the SOLVE mode, algebraic expressions are entered free hand using an internal keyboard which limits entries to the five common mathematical operators (+ - / * ^) as well as one level of parenthesis. There is a maximum term limit of ten variables, but no limit to their magnitude in this mode. In the QUIZ mode, between two and ten variables can be selected, their maximum value and which operators that are eligible. The program then randomly generates an algebraic expression using these parameters. Both modes make available an analysis page which is used to step through the solution. Stack/Queue dynamics are displayed.
