### BODMAS RULE

BODMAS RULE:We must remember the word VBODMAS in solving sums on simplification. These letters stand for vinculum, bracket, of, division, multiplication, addition and subtraction respectively.The sums on simplification must be solved in that order i.e., first solve vinculum followed by bracket and so on until the sum is solved.

### Important Maths Formulas | Area Formulas

a is the corresponding altitude Area of Parallelogram: The number of square units it takes to completely fill a parallelogram.
Formula: Base × Altitude
12. Area of a Rhombus Formula = b . a
where
b is the length of the base
a is the altitude (height). 13. Area of a Trapezoid Formula = The number of square units it takes to completely fill a trapezoid.
Formula: Average width × Altitude The area of a trapezoid is given by the formula where
b1, b2 are the lengths of each base
h is the altitude (height) 14. Area of a Sector Formula (or) Area of a Sector of a Circle Formula =  πr2(C360)
where:
C is the central angle in degrees
r is the radius of the circle of which the sector is part.
π is Pi, approximately 3.142 Sector Area – The number of square units it takes to exactly fill a sector of a circle.

Area of a Segment in Radians A=1/2×r2(θ−sinθ)
Area of a Segment in Degrees A=12r2(π180θ−sinθ) Area of a Segment of a Circle Formula
16. Area under the Curve Formula:
The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b, integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.  ### Algebra Formulas | Maths Formulas

### Root Maths Formulas

Square Root :
If x2 = y then we say that square root of y is x and we write √y = x
So, √4 = 2, √9 = 3, √36 = 6

Cube Root:
The cube root of a given number x is the number whose cube is x.
we can say the cube root of x by 3√x

• √xy = √x * √y
• √x/y = √x / √y = √x / √y x √y / √y = √xy / y.

### Fractions Maths Formulas

What is fraction ?
Fraction is name of part of a whole.

Let the fraction number is 1 / 8.

Numerator : Number of parts that you of the top number(1)

Denominator : It is the number of equal part the whole is divided into the bottom number (8).
