This Glossary contains 20 Mathematical Formula and their roles.
Addition
noun
It is a basic mathematical operation that involves combining several numbers or quantities into a single number.
Example: In addition to my low income, I have some difficulties repaying the bank, means this problem will take some time to resolve.
fr: addition
Algebra
noun
A combination of numbers (constants), letters (variables), and mathematical operation symbols.
Example: In this exercise, algebra will help you find the missing values.
fr: algèbre
Angle protractor
noun
A measuring instrument used to measure, draw, or transfer angles in degrees.
Example: To find the measure of the angle in this triangle, you need to use an angle protractor.
fr: rapporteur d'angles
Calculator
noun
A device designed to automatically perform arithmetic or mathematical operations.
Example: During a math test, each student uses a calculator to perform mathematical operations more quickly.
fr: calculatrice
Derivative
noun
It measures the rate of change of a function with respect to changes in its variable.
Example: By analyzing the derivative of this function, we can precisely determine its instantaneous rate of change.
fr: dérivée
Division
noun
It is the act of dividing a whole into several parts, or a mathematical operation involving division.
Example: We need to think of this situation as a mathematical division problem and seperate this cake into equal pieces.
fr: division
Exponent
noun
It is a number, letter, or symbol written in small print in the upper-right corner of a quantity to indicate the power to which it is raised.
Example: My homework is piling up exponentially.
fr: exposant
Fraction
noun
It is a number that represents a part of a whole or the division of a quantity into equal parts. It is possible to obtain a decimal number such as 1/3.
fr: fraction
Geometry
noun
Geometry studies figures, shapes, surfaces, and volumes in a plane or in space.
Example: This glass table is a pentagon, which is a geometric shape.
fr: géométrie
Integral
noun
A mathematical operation that involves summing an infinite number of small quantities to calculate a total value, such as the area under a quadratic function.
Example: To calculate the total area under this quadratic function, we must find its integral between these two points.
fr: intégrale
Linear function
noun
A mathematical function that maps every number x to the product of that number and a constant a, written as f(x) = ax
Example: Our income is increasing at a linear rate.
fr: fonction linéaire
Logarithm
noun
It is the exponent to which a fixed number (called the base) must be raised to obtain a given number. It is the inverse of the exponential function.
Example: The logarithm is the ideal mathematical tool for measuring phenomena on a very large scale, such as the sound levels in decibels.
fr: logarithmique
Mass-energy equivalence
noun
This formula indicates that mass and energy are two forms of the same physical entity.
Example: Applications of the mass-energy equivalence principle paved the way for nuclear power generation.
fr: équivalence masse-énergie
Multiplication
noun
It is a mathematical operation that involves repeating a number several times ans adding it to itself.
Example: The amount of my homework is increasing at the rate of a multiplication problem.
fr: multiplication
Percentage
noun
It is the probability that an event will occur, for calculating grades, interest rates and more.
Example: It is difficult to calculate the interest rate percentage.
fr: pourcentage
Pi
noun
A mathematical constant that represents the constant ratio of a circle's circumference to its diameter.
Example: There is an important difference between a pie and the number pi. A pie is a dessert, while the number is related to a circle and its circumference.
fr: pi
Ruler
noun
An instrument used to draw straight lines or measure the length of a line.
Example: For this exercise, you will need a graph to interpret this linear function using the given numerical values. You will need a ruler to draw the graph.
fr: règle
Square root
noun
The square root of a positive number is the only positive number whose square equals that number.
Example: To calculate the length of a square's side based on its area, you need to find its square root.
fr: racine carré
Substraction
noun
It is a mathematical operation that involves subtracting one quantity from another in order to compare two numbers.
Example: When an item is on sale, we need to use subtraction to calculate the difference between the final price and the discount percentage.
fr: soustraction
Trigonometrical circle
noun
A circle with a radius of 1 unit, whose center is at the origin (0,0) of a Cartesian plane.
Example: When you plot an angle on the unit circle, you can read its cosine directly from the x-axis and its sine directly from the y-axis.
