The area of a triangle is described as the whole area enclosed by the \(3\) sides of any particular triangle. Essentially, it’s equal to half of the \(base \times height\), i.e. \(A \ = \ \frac{1}{2} \times b \times h\).

Simple Interest is a basic technique for determining the interest rate for a loan/principal amount. Simple interest is a model utilized in a lot of places, like banks, finance centers, automobile loans, etc. Whenever you make your loan payment, in the beginning, it goes toward the monthly interest, then the rest pays on the amount of the principal.

Another interesting type of ratios is the proportional ratios. If two distinct ratios can be simplified into the same fraction, then they are said to be proportional ratios. Suppose we have two ratios as \(1 \ : \ 2\) and \(2 \ : \ 4\).

In mathematics, sometimes we are presented with a set of complex equations containing lot of operations. So, to sequentially and correctly solve the equation, we apply the order of operations. The order of operations tells the sequence in which the multiple operations in the mathematical expressions should be solved.

To simplify a polynomial expression, apply the below-mentioned steps:

• First, simplify the expression by adding/subtracting the like terms.
• Also, wherever possible, use the distributive property.

Check the entities in the given problem for writing ratios. Then divide both sides of the ratio to simplify it further. Suppose there are \(14\) apples and \(7\) oranges. So, the ratio of apples to oranges would be \(\frac{14}{7} \ \ = \ \ 14:7 \ \ = \ \ 2:1\).

To add or subtract two integers, follow these steps:

• In the first case, if two integers have the same sign (either both are positive or both are negative), add up those integers and put the common sign.
