“Can you solve this without a calculator?” reads the caption to this brain teaser shared on X by a user Dr Saba Osmaan. The brain teaser asks a seemingly simple question: ‘Can you solve this?’ the accompanying equation is ‘2×1+6×6’. Simple, right? But can you solve it in 10 seconds or less and prove your calculation skills? Your time starts now…
Take a look at the brain teaser shared on the micro-blogging platform below:
The brain teaser was shared a day ago and has been viewed by more than 1,400 people. Many of them liked it. Additionally, a few even tried solving it and shared their answers in the comments.
ANSWER:
Here’s what people posted after solving this brain teaser:
An individual wrote, “PEMDAS rule 2+36=38.”
Another added, “Yes, I can solve this question without a calculator. 2×1 + 6×6 =2 + 36 =38.”
“According to BODMAS 38,” joined in a third.
A fourth commented, “You all are right. Cheers.”
Many unanimously agree that ‘38’ is the correct answer to this intriguing brain teaser.
Were you able to solve this maths-related brain teaser? If yes, what answer did you get?
Earlier, a maths brain teaser was doing the rounds on the Internet. It claimed that 99% of people won’t be able to solve it correctly. The challenge was to find the product of two numbers. Intriguing, right?
Recently, a new type of challenge has appeared on the net, although the quizzes themselves are not particularly new.
It’s about good old-school mathematics.
Trying this kind of challenge is exciting and fun, especially if it has been a bunch of years since you last went to school.
It’s important to think about it and try to remember those old rules of math your teacher kept writing on the chalkboard many years ago.
In addition, you must exercise your competitive instinct as well, which is always fun.
Can you figure out the solution for this math riddle – without a calculator?
Okay, now onto the challenge itself.
In the picture below, we see a mathematics problem made for middle schoolers.
The challenge: are you able to solve it without a calculator?
Remember the order of operations. What part should you solve first?
Think about it carefully so you answer correctly!
Below the next picture, you will find the correct answer.
Here’s the answer.
In evaluating the expression 6-1×0+3÷3, we use the PEMDAS mnemonic device, which tells us the correct operator precedence.
So applying theory to your question, we must evaluate the multiplication and division operations first, then the addition and subtraction. Therefore:
6-1×0+3÷3
= 6-(1×0)+(3÷3) [items within parenthesis are evaluated first]
= 6-0+1
= 7
The answer is then 7.
Did you get it right? Congratulations!
