In a world where calculators and smartphones are always within reach, it’s easy to forget how powerful your brain truly is. That’s why puzzles like this one have become a fun and engaging way to challenge your mental math skills and keep your mind sharp.
The challenge? Solve the following equation without using a calculator:
3 × 3 + 3 + 3 – 1 + 3
At first glance, it might look a bit tricky. The mixture of multiplication and addition/subtraction is meant to throw you off. But with a clear mind and a little order of operations knowledge, you’ve got this!
Step-by-Step Breakdown
To solve this correctly, remember the order of operations, often remembered by the acronym PEMDAS:
-
P: Parentheses
-
E: Exponents
-
MD: Multiplication and Division (from left to right)
-
AS: Addition and Subtraction (from left to right)
Let’s apply this to the problem:
3 × 3 + 3 + 3 – 1 + 3
-
Start with the multiplication:
-
3 × 3 = 9
-
-
Now plug that back in:
-
9 + 3 + 3 – 1 + 3
-
-
Solve from left to right:
-
9 + 3 = 12
-
12 + 3 = 15
-
15 – 1 = 14
-
14 + 3 = 17
-
Final Answer: 17
This simple-looking equation is a great reminder that the correct answer depends entirely on using the right steps in the right order. Many people might rush and get a different answer—especially if they overlook the multiplication.
