Most people study mathematics in their various institutions and secondary school and solve a lot of unknown equations, mathematical problems but yet they don't know the abbreviations attached to what they solve.

That is the reason I will list out important abbreviations you all need to know about why solving this wonderful mathematics.

Below are the important abbreviations;

1. BODMAS - Bracket Of Division, Multiplication, Addition and Subtraction.

2. BIDMAS - Bracket of Indices, Division, Multiplication, Addition and Subtraction.

3. Cos - Cosine:

It is a basis of trigonometry where two right triangles have equal acute angles and are similar, so that their side lengths are proportional.

4. Adj - Adjugate:

When you learn linear algebra, the adjugate or adjoint of a square matrix is the transpose of its cofactor matrix. But, "adjoint" of a matrix now refers to its corresponding adjoint operator, which is known as the conjugate transpose.

5. Cosh - Cosine Of Hyperbolic Functions:

In mathematics, hyperbolic functions are analogs of the ordinary trigonometric functions.

6. Grad - Gradient

It is known as the direction of greatest change of a scalar function.

7. Var - Variance:

It is the expectation of the squared deviation of a random variable from its mean.

8. Tan - Tangent:

It is also a basis of trigonometry just like sine and cosine that involves two right triangles that have equal acute angles and are similar then their side lengths are proportional.

9. RHS - Right Hand Side:

It is the right side of an equation that is given to you to simplify.

10. LHS - Left Hand Side:

It is the left side of an equation that is given to you to simplify.

11. Log - Logarithm

It is the inverse function to exponentiation meaning that, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

12. Iff - If and Only If:

It is a mathematical expression used as a biconditional logical connective between statements, where either both statements are true or both are false.

13. RMS - Root Mean Square.

14. Sin - Sine

It is a basis of trigonometry too.

15. Eqn - Equation.

Bluetooth technology is a standardized short-range wireless communication technology that uses a low-power radio frequency with low cost to transfer files. It is interoperable & it sucks up very little energy, It is a special wireless communication system that allows completely different electronic devices to communicate with each other. Most new phones and computers come with Bluetooth connectivity.

Bluetooth can work between any two bluetooth enabled device whether it’s Mobile phone, Computer or other electronic devices. It does not require additional connectivity such as internet connection, wireless network or routers. The only limitation of using bluetooth is that it can only be used over short distance and when transferring files, it takes longer time to be completed.

Most mobile users use their phones’ bluetooth for sending small files only, but unknown to them, there are other importance of bluetooth beyond sending files. Here are other things you can do with your phone bluetooth apart from file sharing:

As we all know, a 100% attention is needed from someone while driving because any distraction can have a serious consequences. The bluetooth technology can be used to connect the mobile phone to the car speakers, and a driver doesn’t need to hold his phone while receiving call when he is driving

Most bluetooth enabled mobile phones can be used to share internet connectivity using the bluetooth tethering technology. This allows the mobile phone to share its internet connectivity with a connected device like a laptop or another mobile phone.

Another unkown features about bluetooth by most users is Audio streaming. If your phone is bluetooth enabled you can connect to another mobile and stream the Audio in the second phone without sending the files to your phone.

Bluetooth enabled phones can be connected to a computer device and without needing a USB cable, you can synchronise your files via the bluetooth.

With a bluetooth connection, Siri (An iOS application) or its android counterpart can give you you direction to your destination without needing any help from anybody.

These are the five other things that you can use your bluetooth for. If you have additional usage you can add it in the comment section.
