Important Formulas: Algebra

## Important Formulas

(1) The letters which are used to represent numbers are called literal numbers or literals.
(2) The literal numbers themselves as well as the combinations of literal numbers and numbers obey all the rules (and signs) of addition, subtraction, multiplication and division of numbers along with the properties of these operations.
(3) x X y = xy, 5x, 1 X x = x, x X 3 = 3x
(4) aX a X.......X12times = a12, y X y X....X 15times = y15.
(5) In x9, is called the index or exponent and x is called the base. In a5 , the index or exponent is 5 and the base is a
(6) A symbol having a fixed numerical value is called a constant.

## FAQs on Important Formulas: Algebra - Mathematics (Maths) Class 6

 1. What are some important algebraic formulas that are taught in Class 6?
Ans. Some important algebraic formulas taught in Class 6 include: - Formula for calculating the area of a rectangle: Area = length × width - Formula for calculating the perimeter of a rectangle: Perimeter = 2 × (length + width) - Formula for calculating the area of a triangle: Area = ½ × base × height - Formula for calculating the perimeter of a triangle: Perimeter = side1 + side2 + side3 - Formula for calculating the area of a circle: Area = π × radius²
 2. How do you calculate the area of a rectangle?
Ans. To calculate the area of a rectangle, you multiply the length of the rectangle by its width. The formula for the area of a rectangle is Area = length × width.
 3. What is the formula for calculating the perimeter of a triangle?
Ans. The formula for calculating the perimeter of a triangle is the sum of the lengths of its three sides. So, Perimeter = side1 + side2 + side3.
 4. How do you find the area of a circle?
Ans. To find the area of a circle, you multiply the square of its radius by π (pi). The formula for the area of a circle is Area = π × radius².
 5. What is the formula for calculating the area of a triangle?
Ans. The formula for calculating the area of a triangle is half the product of its base and height. So, Area = ½ × base × height.
