- complete statistics of solved tasks, allowing you to see which tasks caused difficulties or took a lot of time, and which ones were easy to cope with.

- "disappearing condition" mode for enhanced memory and attention training.

The application "Math in mind" is designed to train mental counting at any age. It can be used by both children who study mathematics at school and adults.

• MATHEMATICS FOR PREPARATION FOR THE OGE AND THE USE

• MATHEMATICS FOR UNIVERSITY APPLICANTS

• OLYMPIAD MATHEMATICS

Oral counting can be useful in preparing for state exams in mathematics - OGE 9th grade and USE 11th grade, at olympiads and entrance exams.

Any such activities are demanding on the speed and accuracy of mathematical calculations, so a little daily practice using the mental arithmetic simulator "Math in Mind" will allow you to keep this useful skill at a high level.

• MATHEMATICS IN SECONDARY SCHOOL GRADE 5-6

• MATH IN HIGH SCHOOL GRADE 7-11

In secondary school (grades 5 and 6), the main content of education is percentages, common and decimal fractions, negative numbers, word problems. In high school (grades 7-11), students study algebra, geometry and stereometry, which are filled with a huge amount of material: equations, inequalities, roots, logarithms, reduced multiplication formulas, derivatives, axioms and theorems, areas and volumes.

Without strong numeracy skills, students require too much time and attention to perform computational operations, and because of this, they do not have time to focus on the essence of new concepts. Practicing mental counting allows you to avoid computational errors and helps in mastering new topics. Mental counting skills will be useful in solving problems in physics, chemistry, biology, computer science, economics and astronomy.

• MATHEMATICS IN PRIMARY SCHOOL FROM 1 TO 4 GRADE

The oral counting simulator corresponds to the school curriculum and GEF. For elementary math grades 1-4, select the difficulty settings you want in the app, from single-digit addition, subtraction, multiplication, and division, including the multiplication table, to double-digit multiplication and division. The final work for the elementary school course (VLOOKUP in mathematics) can use all arithmetic operations at all levels of complexity.

• MATH FOR ADULTS

Mathematics for adults is very popular as an excellent training of memory, attention, intelligence training. Mental counting is the most accessible mathematics for adults, requiring no prior knowledge and skills. And besides everything, mental calculations are a real pleasure from how the world of numbers conquers you :)
