Then take pleasure in doing the test of the day, because it only brings you good!
Visual test: “Can you find the answer to this equation? »
In order to test your math skills, we have chosen a series of operations that requires a lot of attention and a great sense of logic.
Are you ready to rack your brains? Discover your riddle of the day below:
18÷3 (5-4 +1) = ?
We encourage you to try to solve it yourself before viewing the answer. Please note, you do not have the right to ask for help from a person or the internet. Try to solve this riddle with your own skills.
Especially since you have no time constraints this time. However, if you want to measure your analysis and logic speed, you can always start your timer.
IQ test: The correct answer
Did you give the correct answer? Well done ! This means you are still a math whiz. To maintain your skills, train your brain regularly with challenging exercises like this. You will find variations of this type of test on our site.
Have you forgotten which calculation takes priority between parentheses, multiplications and additions?
It’s because you’re a little rusty when it comes to math! Remember the concept: PEMDAS. This is a trick for remembering the order of priority of operations: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.
The solution
So, to calculate today’s test, you must start by solving the operation in parentheses, then perform the multiplication then the division.
Indeed, as addition and subtraction are in parentheses, they are done first and not downstream. Also, operations must be carried out from left to right.
So you had to do the following:
18÷3 (5-4 +1) = 18÷3 (1 +1) = 18÷3 (2) = 6 (2) =12
The solution to today’s math puzzle is therefore 12.
Don’t hesitate to give this brain challenge to your friends and family members to assess their math and logic skills. This test is also suitable for children to introduce them to complex calculations.
