How to align equations by equal sign in MS Office Word

Recently, actually a few minutes ago, one of my friends asked me how to align equations by their equal signs. He wanted to align all equations by their equal sings. (You can clearly see what I'm talking about in the image below. I have typed four equations and they are not aligned by their equal sings.)

1. The first thing we want to do is to avoid typing these equations as separate equations. Yes, that is what we always do. We type the first equation and hit the big enter button, and then we type the second one and hit enter, and we type the third one... so on. But in our case, we have to type all these equations in one box.
   But how to do that? It's easy, we just have to press shift + enter, instead of pressing enter, at the end of the equation. (Just cut and paste if you already have typed all the equations as individual ones.) 
   
   Note!
   
   What happens here is that when you press shift + enter it creates another line for the same equation. So it looks like a new equation but it is the same equation but in a separate line
2. Now we have typed our equations in the correct way. Now the easy part. The next thing we have to do is to move our mouse pointer to the left of the equal sign of the first equation and left click there. Now you can see the cursor is blinking there like below.
   
3. Now right-click there and choose Align at this Character option and left-click on it. You have do repeat this for all our equations.

That's it. As we are going through this process we can see each equation gets aligned automatically just after we click 'Align at this Character' option. In the end, we can see a clean set of equations as shown below.

NOTE!

If your equations are still not aligned properly just change your paragraph alignment options. This can happen as we are typing equations under different alignment options.

Thank you for reading this and I hope you found something useful from this post. And actually, this is the first blog post I posted.
