Types of Interest in Math

Interest is classified into two types. They are:

Simple interest

Compound interest

Simple interest: Simple interest is money we can earn by primarily investing some amount in bank or somewhere else (the principal). The percentage (the interest) of the principal amount is added to the principal, simple interest will increase our initial investments grow.

Compound interest: The difference between the original principal and the amount at the end of the last time period is known as the compound interest on the original principal period for that.

The important difference between compound and simple interest is  that simple interest is paid only on the principal, whereas compound interest is paid on both the principal and the accumulated interest.


Interest formula


Simple interest formula:

The formula used for calculating the simple interest is

SI = `(PNR)/100`

Where,

P is the Principal,

N is the time period,

R is the rate of interest.

Compound interest formula:

The formula used for calculating the compound interest is

A = P (1 + `r / 100` )n

Where,

P is the Principal

R is the rate of interest

N is the number of years.


Solved Examples


Pro 1: Find the simple interest on an amount of $500 for one year at the rate of 6% per annum.

Sol: The formula is SI = PNR / 100

Principal (P) = $500

Rate of interest(r) = 6 % per annum

N= Interest on 100 dollar for 1 year = $6

Interest on 500 dollar for 1 year =6 / 100 × 500 = $30

Therefore the interest is $30.

Pro 2: Find the amount of and compound interest on $6000 for 3 years at 3% per annum.

Sol: Let p1, p2, p3… represents the principal for the first year, second year, third year and so on. Also let I1, I2, I3… represent interest for the first year, second year, third year and so on.

Understanding Definition of Compound Interest is always challenging for me but thanks to all math help websites to help me out.

The formula is A = P (1 +` r / 100` )n

C.I. = A – P

P = $6000, r = 3%, n = 3 years

A = P (1 + `r / 100` )` ^n ` = 6000 (1 + `3 / 100` )3

= 6000 (`103 / 100)` 3

= 6000 * 103 * 103 * 103 / 100 * 100 * 100

= 6556.36

Therefore

A = $6556.36

P = $6000

C. I. = A – P = 6556.36 – 6000 = 556.36
C. I. = $556.36

Pro 3: Find the amount and compound interest on 5000 dollars for 1.5 years at 8%per annum. Interest being is added to the principal every half year.

Sol: P = 5000dollars, n= 3 (three half years), r = `8/ 2` = 4%

A = P (1+`r / 100)` n = 5000 (1+4) / 100 3

= 5000 (`104 / 100` )3

= `(5000*104*104*104) / (100*100*100)` =5624.32dollars

A = 5624.32

Compound Interest = A – P = 5624.32 – 5000

= 624.32dollars.

Pro 4:  Find the solution of simple interest, where total amount is 80,000, rate is 0.04 for per annum.

Sol: Simple interest = P*N*R.

=80000 *0.04 * 1.

=3200.

The simple interest is 3200.

Pro 5: Find the solution of simple interest, where total amount is 1,00,000, rate is 0.09 for per annum.

Sol: Simple interest = P*N*R.

=1,00,000 *0.09 * 1.

=9000.

The simple interest is 9000.

Math Terms Division

Introduction to math terms division:
In mathematics, especially in elementary arithmetic, division (÷) is the arithmetic operation that is the inverse of multiplication.

Specifically, if c times b equals a, written: C = b x a

where b is not zero, then a divided by b equals c, written: `a/b = c`

For instance, `6/3 = 2`

since  2 x 3 = 6

In the above expression, a is called the dividend, b the divisor and c the quotient. I like to share this Simplify Algebraic Expressions with you all through my article.


Math terms division:


Math term division type -1:

Division of 2 numbers with the same sign should be ‘+’ ve (positive sign) sign.

‘+’ve (Positive number) ÷’+’ve ( positive number) = ‘+’ve ( positive number)
‘-‘ve (Negative number) ÷ ‘-‘ ve (negative number) = =’+’ ve (positive number)
Math term division type - 2:

Division of 2 numbers with different signs should be ‘-’ve negative

‘+’ve (Positive number) ÷(‘-‘ve negative number) = ‘-‘ve (negative number)
‘-‘ve (Negative number) ÷ ‘+’ve (positive number) = ‘-‘ve (negative number)
Examples on math terms division :

Ex : 42 ÷ 7 = 6 (same signs)

(-26) ÷ (-2) = 13 (same signs)

6 ÷ (-2) = -3 (different signs)

(-10) ÷ 10 = -1 (different signs)

Math Terms Division on Dividing Variable:
In this operation division represents dividing the variables based on the presence of values.

Ex: Solve the following division: 54 ÷ p, given that p = -6

Solution:54 ÷ p

Substitute p = -6,

= 54 ÷ (-6)

= -9 (dissimilar signs).

Math Terms Division Of Dividing Decimal:


Math terms division for solving decimal problems:

Math term division of decimals type - 1:To create the decimal divisor as whole number by changing the decimal point to the right side.
Math term divison of decimals type - 2:To change the same decimal point in the dividend to the right side to create as whole number
Math term  division of type - 3:After divide the new dividend or whole number by new divisor or whole number


Ex:Divide the following decimal function:  24.24 ÷ 0.20

Solution:   24.24 ÷ 0.20 = `24.24/0.20`

= `242.4/2`  (Take the decimal divisor as whole number)

= `2424/20`  (Take the decimal dividend as whole number)

= 121.2 (Divide the new dividend by new divisor).

How to Study For Algebra

Algebra is the division of mathematics concerning the revise of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. For example:

x - 6 = 2

x – 6 + 6 = 2 + 6

x + 0 = 8

x = 8 (the answer)

The algebraic statements that explain relationships are expressed using algebraic terms, expressions, or equations. Earlier than we use algebra to find information about these kinds of relationships, it is important to first covers some basic terminology.

Algebraic Expressions


An expression is a significant group of numbers, variables, and signs, positive or negative, of operation that must make mathematical with logical sense. Expressions:

• contain any number of algebraic terms

• Use symbols of operation—addition, subtraction, multiplication, with division.

• do not contain an equality sign (=)

Example for an expression is:

–4ax + 5wx^2y

In an expression, the symbols of operation separate it into terms. The symbol also becomes part of the term that it follows. The expression more than contains two terms, the first term is –4ax and the second term is +5wx^2y. The addition sign separates the two terms. For example, in the term given above the plus sign (+) separates the –4ax from 5wx^2y and is also part of the second term. Conditions that do not have a sign listed in front of them are understood to be positive. I have recently faced lot of problem while learning Math Parallel Lines, But thank to online resources of math which helped me to learn myself easily on net.


Terms and Factors


A word in an algebraic expression is an expression concerning letters and/or numbers (called factors), multiplied together.

Example 1:

The algebraic expression

9x

is an example of one single term. It has factors 9 and x.

The 9 is called the coefficient of the expression.

Example 2:

5x + 3y have two conditions.

First term: 5x, has factors 5 and x

Second term: 3y, has factors 3 and y

The 5 and 3 are called the coefficients of the conditions.

Like Terms

"Like terms" are terms that enclose the same variables raised to the same power.

Examples

3x^2 and 7x^2 are like terms.

-8x^2and 5y^2 are not like terms, since the variable is not the similar.

First Quadrant

Definition:

The x- and y- axis divides the coordinate plane into 4 regions. These regions are called the quadrants.

Each quadrant bounded by two half-axes. These are often numbered from first to fourth and denoted by Roman numerals: I (where the signs of the two coordinates are (+,+), II (-,+), III (-,-), and IV (+,-). When the axes are drawn according to the mathematical form, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.


Cartesian coordinate system


A Cartesian coordinate system specifies each and every point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length.

Each reference line is called a coordinate axis of the system, and the point where they meet is its origin. The coordinates are also defined as the positions of the perpendicular projections of the point onto the two axes, expressed as a signed distances from the origin.

Cartesian coordinates can be used to point out where you are on a map or graph.
