Why You Should Do More Brainteasers?

Brainteasers are a fantastic way to keep your brain active. They encourage you to think on your feet and allow you to see how fast you can solve easy problems. The more you complete brainteasing exercises, the faster you will do them. You will find that this practice can facilitate your day-to-day mental math and leave you feeling accomplished when you can easily check your total on a restaurant bill or monitor your spending.

Brainteasers can also help with the sentiment of restlessness that may come with spending days in a repetitive routine. They will have you work those neurons to arrive at solutions, which can give you a surge of dopamine and even endorphins, the pain-relief hormones. After completing brain exercises, you will find that you are more relaxed, less anxious, and quite satisfied with yourself. This can help you sleep better and even improve your mood.

Finding The Solution 

Here is how to dissect this equation: 150 – 2 (2 + 5) ² =?

First things first: you will want to start with solving the addition in the brackets

150 – 2 (7) ²

Once you have done that, you will need to square the number in the brackets:

150 – 2 (49)

You will then need to solve the multiplication to get your final equation:

150 – 98

This will provide you with your final answer: It’s 52.
