# What is the math formula?

What is the math formula? The formula is a fact or a rule written with mathematical symbols. It usually connects two or more quantities with an equal to sign. When you know the value of one quantity, you can find the value of the other using the formula.

## What is algebra formula?

Algebraic equation, statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root. Examples are x3 + 1 and (y4x2 + 2xy – y)/(x – 1) = 12.

## What is percentage formula?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

## What are the 3 types of equations?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

## Who is the father of mathematics?

Archimedes is considered the father of mathematics because of his notable inventions in mathematics and science. He was in the service of King Hiero II of Syracuse. At that time, he developed many inventions. Archimedes made out a pulley system designed to help the sailors move objects up and down that are weighty.

## What is a B formula?

( a + b ) ( a − b ) = a 2 − b 2. It is read as the plus times minus is equal to the squared minus squared.

## What is the formula of trigonometry?

It says that c2, the square of one side of the triangle, is equal to a2 + b2, the sum of the squares of the the other two sides, minus 2ab cos C, twice their product times the cosine of the opposite angle. When the angle C is right, it becomes the Pythagorean formula.

## What is discount formula?

The formula to calculate the discount rate is: Discount % = (Discount/List Price) × 100.

## What is degree formula?

Yes, we can convert negative radian to a degree using the radian to degree formula. The formula is Degrees = Radians × 180 / π and it can be used for both positive and negative values.

## What is fraction formula?

An equation in which one or more terms is a fraction is called a fractional equation. … We can do this because multiplying both sides of an equation by the same quantity (the LCD in this case) does not unbalance the equation. With the fractions thus eliminated, the equation is then solved as any nonfractional equation.

## What are the 5 types of equations?

Different Types of Equations

• Linear Equation.
• Exponential Equation.
• Rational Equation.

## What is standard form in math?

Answer: Standard form meaning is maths is defined as representation or notation of that particular element. It depends on the subject whether it is numbers, an equation or a line. Explanation: The standard form of a straight line is Ax + By = C. The standard form of a quadratic equation is ax2 + bx + c.

## What is standard form slope?

Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as Ax+By=C. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. … A, B, C are integers (positive or negative whole numbers) No fractions nor decimals in standard form. « Ax » term is positive.

## Who invented math?

The earliest evidence of written mathematics dates back to the ancient Sumerians, who built the earliest civilization in Mesopotamia. They developed a complex system of metrology from 3000 BC.

## Who invented 0?

The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.

## Who is the first mathematician?

One of the earliest known mathematicians were Thales of Miletus (c. 624–c. 546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed.

## What is the formula for calculating?

## What is a 2 B 2 formula?

The a2 – b2 formula is also known as « the difference of squares formula ». The a square minus b square is used to find the difference between the two squares without actually calculating the squares. It is one of the algebraic identities. It is used to factorize the binomials of squares.

## What is a 2 B 2 called?

It ended up very simple. And it is called the « difference of two squares » (the two squares are a2 and b2). This illustration shows why it works: a2 − b2 is equal to (a+b)(a−b)

## What is a formula example?

A formula is an expression telling the computer what mathematical operation to perform upon a specific value. In the picture below is an example of a Microsoft Excel formula =SUM(A\$1:A\$3), which adds the total of cells A1, A2, and A3. … In this formula, SUM is the function of the formula.

## Who is the father of trigonometry?

The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. This makes Hipparchus the founder of trigonometry.
