Due to the COVID-19 pandemic, following the social distancing guidelines, many people are isolated in their homes facing the problem of how to kill time.
Here are some activities that people are doing:
- Reading tons of books
- Watching films on Netflix
- Trying skills in the kitchen
- Gardening or some DIY projects
We offer you something different, to solve a math problem.
For many people, Math is a mysterious subject in school, and they are trying to avoid it whenever was possible. However, later in their life, they would all realize that it is very important, as they need to apply Math in numerous real-world situations. Math is excellent for the brain of people as it improves their problem-solving skills and can also help them with their finances.
Try testing your mental ability with math puzzles, because they combine logic and math. Practicing on puzzles will make your brain active and your mind will clear up quickly.
By following the rules of mental math solve the next equation:
50 + 50 – 25 x 0 + 2 + 2 =?
If you haven’t got the result 104 do not despair, as many people are doing that wrong.
When you solve Math problems you should follow the rules of basic math and the order of operations needed for completing equations.
Always keep in mind an acronym BEDMAS:
B – brackets
E – exponents
D – division
M – multiplication
A – addition
S – subtraction
If you fall in solving this Math equation, try completing the next one:
8÷2 (2+2) =?
When that equation was posted on Twitter, users started arguing about the answer, and the arithmetic problem quickly went viral and users citing fundamental principals in math, some insulting the others, and math majors arguing over it.
- 8÷2(2+2) =16,
- 8÷2(2+2) =1.
There were many attempts by using the scientific calculators to prove their answer is right. Some of the users used their degrees to indicate they cannot be wrong, while some gave up quickly after they realized it is not a simple math problem.
Very interesting is the reaction of some people who claimed that both answers are correct!
What did experts say about it?
According to the experts, the answer depends on where one has studied math. So, the PEMDAS method, the operations are ordered like this: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
So, you’d do 8 divided by 2 first, which is 4 and the final result is 16 according to the classic order of operations.
People who got 1 solved the equation using the BODMAS method: Brackets, Orders, Division, Multiplication, Addition, Subtraction.
Mike Breen, the public awareness officer for the American Mathematical Society, explains that no one is wrong, as it has been ambiguously written in the first place.
According to Dr. Thomas House, a lecturer in Applied Mathematics at the University of Manchester, it depends on definitions of things, so when writing computer code the first interpretation would normally be written (8/2)*(2+2) and the second 8/(2*(2+2)) to avoid any ambiguity.
This phenomenon is known as confirmation bias, which occurs from the direct influence of desire on beliefs.
This should teach everyone that the openness to other people’s beliefs can end up learning something he/she never knew.
