Solve the problem without a calculator
The task below is a classic math problem from primary school. It is important to remember the order of operations if you want to get the right result, which is not easy after all these years.
Below we can see the challenge. Can you solve it?
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.
A
B
C
Here’s the answer.
The correct answer is 11.
How do we know that 11 is the right answer?
To begin with, we need to solve the part inside the parenthesis, 12 ÷ 4 + 1, which equals 4.
After that, the problem looks like this: 15 – 1 x 4. So the next step is to calculate the multiplication, which equals 4.
So the problem now is 15 – 4, which totals 11.
The answer is then 11.
Did you get it right? Congratulations!
