[FREE version]: Chapter 1 can be used free of charge.(* Chapters 2-7: Can be purchased for a fee.)◆ "Mathematics ∞ Mugen Work" is an application for the problem collection of the first grade of junior high school.◆ It will automatically generate questions and answers.・ Chapter 1 Positive and negative numbers1-1 adjustment1-2 power division, exponentiation1-3 four arithmetic operations1-4 Absolute value and size of number1-5 usage: average1-6 set of numbers and four arithmetic operations1-7 prime factorization・ Chapter 2 Character expression2-1 ×, ÷ Omission of symbolAdd 2-2 ×, ÷ symbolItem 2-3, coefficient, adjustment of one character2-4 Adjustment of the linear formula2-5 Linear multiplication and division2-6 Four rules of linear expression2-7 substitution2-8 units2-9 Usage 1: Price, speed2-10 usage 2: ratio2-11 use 3: figure2-12 use 4: Regularity・ Chapter 3 Equation3-1 equality, inequality3-2 Selection of solution3-3 transfer3-4 fractions and proportional expressions3-5 Usage 1: Number and price, excess and deficiency3-6 use 2: speed3-7 use 3: proportional formula, ratio3-8 use 4: cost price, saline solution・ Chapter 4 Proportional and inverse proportional4-1 Proportional to the function4-2 Decision of formula4-3 domain4-4 coordinatesDraw a 4-5 proportional graphProportional formula from the 4-6 graph4-7 Inverse proportional formulaDraw a graph of 4-8 inverse proportionalityInverse proportionality formula from the 4-9 graph4-10 Usage 1: Proportional and inverse proportional4-11 use 2: Graph・ Chapter 5 Plane figure5-1 Drawing of parallel movement5-2 Symmetrical movement5-3 rotation movement5-4 Movement of figures and circles5-5 Drawing of perpendicular bisectorDrawing a 5-6 angle bisector5-7 Perpendicular line drawingUse of 5-8 drawing5-9 Ougi shapeUse of 5-10 Ougi shape・ Chapter 6 Spatial figures6-1 Polyhedron6-2 Regular polyhedron table6-3 Plane determination and 2 straight lines6-4 Plane and straight line, Plane and plane6-5 development view6-6 plane movement, rotating body, projection drawing6-7 Volume of cylindrical prismVolume of 6-8 conical pyramid6-9 Surface area of ​​prismatic cylinder6-10 Surface area of ​​pyramidal cone6-11 ball6-12 Various volumes・ Chapter 7 Utilization and organization of materials7-1 frequency distribution table7-2 Histogram and frequency line7-3 Relative frequency7-4 cumulative frequency7-5 Statistical probability7-6 Mean, median, mode7-7 frequency distribution table and average value, mode<< Introduction of each function >>■ Answer icon: [No answer / Yes answer] can be switched with the touch of a button.■ Print icon: Can be saved to PDF. Printing is possible in cooperation with other apps. Both with and without answers can be printed.■ Touch prohibition icon: Prevents accidental change of problem■ Update icon: Changed all issues. Change the value by random generation.■ Scroll bar: Change font size■ To change the question one by one, tap the question to switch the difficulty level.Green: EasyBlue: NormalPurple: Hard■ To return to the table of contents, tap the Android back button・ Chapters and sections are divided into small parts for each theme.・ Auxiliary teaching materials for cram school teachers and tutors.・ Since questions and answers are automatically randomly generated, students can solve them immediately without having to think about the original questions.・ Since the numerical value of the word problem changes randomly, it is possible to practice similar problems many times.・ Students will be confident because they can solve anxious problem patterns with different numbers.Now you dont have to buy multiple question books for the exercises anymore!(It can also be used by first-year junior high school students. It covers the range of junior high school 1 mathematics.)
