Math puzzles written on lined paper always bring back fond school memories.
Today, we have a simple yet fun math equation to solve together.
The picture shows a handwritten question that asks: “Can You Solve ???”
Below the question, there is a clear mathematical expression: (18 ÷ 3 + 4) × 2 – 5.
There are four options given: a) 11, b) 13, c) 15, and d) 17.
At first glance, it might look a bit tricky because of the different symbols.
However, if you follow the correct order of operations, it becomes very easy.
In mathematics, we use a basic rule called PEMDAS or BODMAS.
This rule tells us which operation to perform first, second, and last.
The letters stand for Parentheses (Brackets), Exponents (Orders), Multiplication and Division, and Addition and Subtraction.
Let us break down the problem step by step using this rule.
First, we must always look inside the parentheses or brackets.
Inside the parentheses, we see two operations: division and addition.
The expression inside is 18 ÷ 3 + 4.
According to the rules, division always comes before addition.
So, we must calculate 18 ÷ 3 first.
When we divide 18 by 3, we get 6.
Now, we replace 18 ÷ 3 with 6 inside the parentheses.
The expression inside the parentheses now becomes 6 + 4.
Next, we complete the operation inside the parentheses by adding 6 and 4.
6 + 4 equals 10.
Great, now we have simplified the whole parenthetical expression to just 10!
Let us rewrite the original equation with this new value.
The equation now looks much simpler: 10 × 2 – 5.
We now have two operations left: multiplication and subtraction.
Following our math rules, multiplication must be done before subtraction.
So, we multiply 10 by 2 first.
10 × 2 equals 20.
Now we substitute 20 back into our equation.
The equation is now reduced to a simple subtraction: 20 – 5.
Finally, we subtract 5 from 20.
20 – 5 gives us 15.
That is our final answer!
Now let us check the given choices in the picture.
Option a is 11.
Option b is 13.
Option c is 15.
Option d is 17.
Our calculated answer matches option c perfectly.
Therefore, the correct choice for this math puzzle is c) 15.
