What is the order of Mathematical operations?

Why we need an Order of Operations

What is 2+3 x 4 -1? You know working from left to right you have, 2+3=5, 5 x 4= 20 and it follows that 20-1=19. Check the answer on a calculator and compare.

But is the calculator giving you a different answer? Or is it your teacher or friend telling you that your answer is wrong?

The above example is one of the reasons why there is a need to have…

Solving Quadratic Equations Using the Factorization Method

Quadratic Equations By Factoring Examples

We will go through quadratic equations by factoring examples. We’ll be looking at that soon but before that let’s get an overview of what a quadratic equation is.

Overview of Quadratic Equations

Any equation of the form,

, where a, b and c are constants and

is called a quadratic equation. Examples of quadratic equations are :

Therefore in a…

The Equation of a Circle

The equation of a circle explained. We all know many examples of things which are circle in shape. Some even say round instead of a circle. Now a circle can be defined as the locus of a point moving in a plane such that its distance from a fixed point is always constant. If that sounds complex to you don’t worry about it at all. The only thing you need to know is how a circle looks like. Now…

How to find the Inverse function

How to find the inverse function. Now lets first understand it. If a function “f” is one-to-one and maps an element “x” in the domain to an element “y” in the range, then the function that maps “y” back to “x” is called the inverse function “f”. It is denoted by

.

Now consider the function f, defined by { (a, b), (c,d) , (e, f) }. If the elements of each ordered pair are interchanged we will…

How to find the range of a function

The range of a function

The range of a function can be described simply as the set of image values. So all the images of the elements in the domain under a certain function form the range of that function. Therefore it can also be defined as the set of values of the dependent variable, “y” which make the independent variable, “x” defined.

The dependent variable is the image that results from…

How to find the largest Domain of a function

The Domain of a function

The domain of a function is the set of all possible values which make the function defined. This set of values exclude any value which makes the function undefined. Let us use the following examples to illustrate how to find the largest possible domain of functions. We will deal only with the real number system. This means that we will consider only values of “real numbers

Functions in mathematics

What are functions in mathematics? A function is a relation in which each element in the domain is mapped onto one and only one member in the co-domain. Thus, for every element of the domain, there is exactly one image in the co-domain. Hold on, before you despair, it isn’t as complicated as you think at all. let’s break it down. Consider the following relations:

The relations above are both…

Types of relations

Types of Relations in math

There are many types of relations in maths. Understanding relations in math will help you appreciate many other math topics as well as programming. Let’s talk about 4 main types of relations. These are many-to-many relation, one-to-many relation, many-to-one relation, and one-to-one relation. We will address them one by one with examples.

Types of relations:…

Relation in math simplified

What is a relation in math? A relation can be defined as the way in which two or more concepts, objects or people are connected.

In many situations of ordinary life, we are concerned with relations which exist between us and others.

Let us consider the following sentences:

Maxwell is the father of Abena

Christabel is the mother of Emmanuel

Arthur is the husband of Belinda

All these sentences…

How to convert numbers to base 10

Let’s find out how to convert numbers to base 10. Do you want to change from binary to base 10? Or do you wish to change from hexadecimal (base 16) to base 10? This article will help you know how to convert numbers to base 10.

It is only natural that we feel more at home using number base 10 than other number bases. Probably due to the fact that we have 10 fingers. There is a nice history behindi…

How to change from base 10 to any Base

How can you change from base 10 to hexadecimal (base 16)? Or how can you convert a number in base 10 to base 2. To change from base 10 to other bases, a method called successive division is used. The given number in base 10 is divided repeatedly by the appropriate base number. The remainders of each division, including zero, are recorded at each stage of the division.

The division stops only…

Number Bases

What are number bases?

What are number bases? Simply put the base of a number is the number of unique digits, including the digit zero, used to represent numbers. It is also called the radix. So for example, if I say I am counting in base ten, it means that the numerical system I am counting in has 10 unique digits. If I say base 5, it means 5 unique digits in the numerical system.

The Math of the Bible - 1914

The Math of the Bible – 1914

This is the first of the series of the math of the Bible. This series mostly deal with calculations in the Bible.

Have you ever heard of someone saying that the world entered into the last days in 1914? Well lets investigate to find out if there are any evidence in the Bible to support that.
