2 + 2 = 4
What comes to your mind when you use this equation in your life? Of course, you take it as an equal sign. How is it possible to write that two integers are similar to one? It is possible with an equal sign that shows equality on both sides of the equation. Suppose there’s not any specific sign to show equality not only in mathematics but in other subjects too. Is it fair then? Not at all; you come up with an imagination that refers to equality in the calculation but doesn’t have any sign to present it in written form. In order to use this sign correctly, you need to understand what an equal sign is and its usage in mathematics. To answer the queries related to type on your PC or android, you need to follow specific steps accordingly.
There are multiple codes of the equal sign while working on the computer. The equal symbol shows the clarity that two things are exactly equal.
Apart from that, there are multiple variants of the equal sign, i.e. (≠), (≡), (==). We’ll discuss all these in our article in order to let you deliver a better understanding of the equal symbol. Without further ado, let’s discuss it in detail.
Having discussed the importance and overview of the equal sign, let’s learn what equal sign is.
It is a mathematical symbol to represent equality in a definite and well-versed manner. As far as its invention is concerned, credit goes to Robert Recorde. He invented this sign in 1557, as per record. In general terms, it shows equality of value between the two expressions and numbers. Apart from mathematics, it is used in other subjects to show the balance irrespective of the no. of integers.
For example, 1 + 3 + 5 = 9
If you analyze this equation, the integers on the left side are more than the right one; 3 on the left and one on the right sides. But, what makes them equal is the value. The total value of left-sided three integers is 9, equal to the right-sided integer value: 9.
Equal is derived from the “æqualis.”
It is a Latin word which meaning is identical, uniform, or equal. This (=) sign became famous after being used in 1557. At some time, (II) was used by some people, then people adopted the current sign. The sign Robert Recorde used in his book in 1557 was much wider than the current one.
Here comes the meaning of the equal sign. Before further discussing, let’s take an example.
X+1 = 2, then it is understood that the value of x would be 1 to balance both sides; otherwise, you must not place the equal sign between these two expressions. If it’s placed, then x has value 1. Apart from that, we can get the x value mathematically in that equation.
X = 2-1
This is how we can calculate the exact value of any alphabet whose value is not given. If values are equal on both sides, then we use an equal side between them. Sometimes you may have seen the approximate sign (≈). It’s due to the minor difference in values that you cannot ignore. For example, 1.999 ≈ 2
Sometimes this difference is ignored knowingly in mathematics when you deal with a large value; this is when the equal sign is used for own feasibility.
We have discussed the equal sign in equations. It is used in measurement too. For example, if you measured a specific body height, length, and width. Now, if you want to measure the volume of that body, then it will be written as follows:
After discussing the equal sign meaning in mathematics, let’s move towards the next portion. You find difficulty typing an equal sign on PC windows, MAC, IPhone, Android, Excel, Word, and PowerPoint.
Let’s discuss one by one how to type an equal sign in all these places.
There are codes for equal signs with their keys that help you reduce your time and understand these keys related to specific codes effectively. The codes and their symbols are mentioned below in the table.
