Hello my dear students, today we will put light on one of the most important property of math i.e. distributive property. The distributive property states the distribution of multiplication over addition. It is defined as:
A (B + C) = AB + AC. Let's take an example to understand distributive property with its help.
7 ( 2 +3) = (7 * 2) + (7 * 3),
7 (5) = (14) + (21)
35 = 35,
In this way we use distributive property . It gives us a way using which we can solve the above type problems easily. Apart from distributive property, two other properties are also present that are commutative and associative. Associative property defines the grouping or association. For addition it defines the rule as a + (b + c) = (a + b) +c; and for multiplication the rule says a * (bc) = (ab) * c. The commutative property refers to the moving things and it states the law for addition as:
A + B = B + A, and for multiplication if states that
AB = BA.
After learning the property let’s have a look on the compound interest. You all know simple interest and how to calculate it, but how many of you know what is compound interest and how to calculate it? Compound interest is the interest that we accrue on the original principal and the accrued interest of a principal deposit. A formula is defined to calculate the compound interest. I will tell you the formula and also how to use it.
A = P (1 + R/ 100) n
Where, A stands for amount,
P is principal amount,
R is rate and
n is time. The compound interest can be calculated yearly, half yearly, quarterly and so on. If compound interest is calculated yearly then time remains as it is given. If it is half yearly then we take time = 1/2 and so on. Let’s take an example to understand it,
P = 50000,
R = 15 %,
N = 2 years,
To determine compound interest, put the values in the above formula:
A = 50000(1 + 15/100)2
A = 50000(115 / 100)2,
A = 5000 * 115/ 100 * 115/100,
A = 66125
In this way we calculate the compound interest. You can directly solve compound interest with help of compound interest calculator. It directly solves the entire compound interest problems. This calculator is available online with other online help like homework help, algebra help, online tutors and etc.
