# Calculators and Converters - Mathematics

## What is math?

It is the science that studies logical reasoning as well as abstract reasoning, it covers the study of spaces, measures and formats of structures, statistics, finance and many other areas.

Search, describe and correlate patterns, forming conjectures that are proven or not using deductive methods. Mathematics can be divided into pure and applied, and is used in the most diverse areas, such as computing, engineering, physics, medicine and many others.

Use our calculators below to facilitate your work and studies. We also have unit converters:

### We can subdivide Mathematics into four large groups, namely:

#### Space and form

Studying the shape and area of geometric structures, learning how to calculate and dimension them. This group can be subdivided as follows:

• Location, two-dimensional and three-dimensional figures;
• Property of triangles;
• Cartesian coordinates;
• Identification and operations with angles;
• Property of polygons;
• Triangle, circle and circumference metric relationships;
• Calculation of the area and perimeter of geometric figures;
• Trigonometric relations.

#### Information processing

Checks analysis patterns that can be comparative or not. This group is related to the contents:

• Interpretation of tables and graphs;
• Types of tables;
• Making tables;
• Chart types;
• Analysis of data contained in tables and graphs;
• Making graphics.

#### Number and operations / algebra and functions

Concentrates the study of numbers and operations, which consequently generates the study of algebra and functions. We can highlight the following contents:

• Count;
• Sets;
• Integer, natural numbers and their operations;
• Rational, irrational numbers and their operations;
• Complex, real numbers and their operations;
• Fractions and their types;
• Decimal numbers and their operations;
• Polynomials;
• Potentiation;
• Percentage;
• Financial Mathematics;
• Directly and inversely proportional quantities;
• Numeric progressions;
• Numerical and algebraic expressions;
• Equations and inequalities;
• Functions and Systems.

#### Quantities and measurements

Studies the measurement standards for quantities, such as acceleration, density, frequency, molar mass, and others. This group is related to the contents:

• Problems related to area calculation;
• Calculation of the perimeter of plane figures;
• Transforms of units of measure;
• Relationships between measurement units;
• Notions of measurement units.
