Flow Chart vs. Data Flow Diagram: What’s the Difference?

Flow Chart vs. Data Flow

Representing data or information visually is crucial for making it easier to understand. This visual representation can also be vital for understanding the steps to take, decisions to make, and possible outcomes depending on the different paths taken. When trying to understand data and information and their respective flows, the two most common tools used … Read more

An introduction to Antilogarithm: Defined and Explained with Examples


Before understanding anti-logarithms, you should know about logarithms. Many years ago, when the calculator or the computer was not invented, the calculation of larger numbers was too difficult.  In 1614 first time Mathematician John Napier introduced Logarithm and to find a logarithm he published the logarithm table. In 1620, the anti-logarithm table was represented by … Read more

How to Find Slope from Two Points?

How to Find Slope from Two Points

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points … Read more

Comparing numbers is a basic concept that we have learned in our primary classes. When we have two numbers or quantities to compare, then we use three basic symbols, they are: Equal to (=) Greater than symbol (>) Less than symbol (<) Let us learn in this article, how to compare two numbers and what sign … Read more

How Do You Find The Discriminant of a Quadratic Equation?

The Discriminant

The Discriminant When does ax2+bx+c=0 have a real solution? Well, we know how to find the solutions using the quadratic formula: x=−b±√b2−4ac2a. That makes it look like we can always get solutions. However, we can’t always exercise a square root! Sometimes you’ll see a negative number under the radical. A negative under the radical means there is no real … Read more
