# Maths of + and -

The simplest thing in Mathematics after counting is addition, followed by subtraction. You may feel both are different, but they are really not, if you know *negative numbers*.

Adding a positive number is same as subtracting negative of the same number.

Alternatively, subtracting a positive number is same as adding the negative of same number.

This works weather you use BODMAS or PEMDAS for your calculation. It leads to the same result.

## Why is it important?

Itโs important because it is very similar to some challenges we face in our everyday life. We make choices on a daily basis. We add and remove things from our schedules and priorities all the time.

We are humans, and with that comes a lot of limitations in our life. We have a limited time on this planet. We can remember only a handful things. We can make only a few meaningful relationships. Even our phones can handle only a limited set of apps at a time.

We can not have it all. So, adding *important things* and removing *non-important things* is *important*.

### 1. Adding positives

Imagine you want to improve your life by incorporating good habits, such as exercise. This is equivalent to adding a positive thing.

### 2. Subtracting negatives

Now imagine you want to improve your life (same goal) by removing bad habits, such as smoking. This is equivalent to subtracting a negative thing.

## Versatility of this rule

a-(-b) = a+b

subtraction is an addition, when you are removing negatives.

This is applicable almost everywhere.

- To get more time, remove unnecessary meetings.
- To make better bonds, get rid of negative relationships
- To use digital space better, remove unproductive apps.

Sometimes, the addition is easier. Sometimes, itโs the subtraction. Doing both simultaneously is every more useful.

Happy *mathing*.
