## How to Do Level 90 on Brain Test: A Step-by-Step Guide

Brain Test is a popular puzzle game that challenges your problem-solving skills and creativity. Level 90 of the game can be particularly tricky, but fear not! In this article, we will guide you through the steps to conquer Level 90 on Brain Test and move forward in your quest for mental prowess.

Understanding the Challenge:

Level 90 of Brain Test presents you with a grid filled with numbers and mathematical symbols. Your goal is to find the missing number that would make the equation correct. Sounds simple enough, right? Well, let’s dive into the steps needed to solve this brain-teasing puzzle.

Step 1: Analyze the Grid

The first step is to carefully analyze the grid and identify any patterns or relationships between the numbers and mathematical symbols provided. Look for any recurring patterns or operations that are consistent throughout the grid. This will help you gain an understanding of the logic behind the equations.

Step 2: Start with the Existing Numbers

Take note of the existing numbers in each equation and try to identify any operations or patterns that would lead to the correct answer. Sometimes, the operations required to obtain the correct answer may not be straightforward. Think outside the box and consider unconventional operations such as combining numbers or using mathematical properties like squaring or square roots.

Step 3: Test Different Operations

If the existing numbers do not lead to an obvious solution, start testing different operations on the numbers to see if they fit the puzzle. Try addition, subtraction, multiplication, and division, but also consider more complex operations like exponentiation or factorial. Don’t worry if your initial attempts fail; trial and error is a crucial part of the problem-solving process in Brain Test.

Step 4: Pay Attention to the Signs

The mathematical symbols in the grid are there for a reason. Take into account the addition, subtraction, multiplication, and division symbols, as they convey important information about the desired operation. For example, a “+” symbol implies that the two numbers should be added together, while a “-” symbol means that one number should be subtracted from the other. Make sure to carefully consider the meaning of each symbol before attempting calculations.

Step 5: Think Outside the Box

Sometimes, the missing number can be found by thinking creatively or in unconventional ways. Look for patterns or alternative interpretations within the grid. Can you rearrange the numbers to form new equations or operations? Don’t limit yourself to traditional mathematical operations or linear thinking. Brain Test often rewards those who think outside the box.

Step 6: Utilize Clues and Hints

If you find yourself stuck and unable to find the missing number, don’t hesitate to use the clues and hints available. Brain Test offers hints to assist you in solving challenging levels. These hints can provide valuable guidance or point you in the right direction. However, if you wish to challenge your problem-solving skills to the fullest, try solving the puzzle on your own first before resorting to hints.

In Conclusion:

Level 90 of Brain Test may seem intimidating at first, but with patience, creativity, and a strategic approach, you can overcome this puzzling challenge. Remember to analyze the grid, test different operations, pay attention to the signs, think outside the box, and utilize any available clues or hints. Face the challenge head-on, and soon enough, victory will be yours. Good luck, and happy puzzling!
