Common Mistakes When Solving Puzzles Like This
Many people make hasty assumptions, which can lead to incorrect answers. Here are a few common errors to avoid:
- Remember the order of operations: multiplication always comes before addition and subtraction. Keep this in mind as you work through the puzzle.
Now, put your reasoning skills to the test and see if you can solve it!
Avoiding Common Mistakes
- Incorrect Assumptions About Object Values: Each object in the puzzle has a fixed value, so it’s crucial not to misinterpret any of the equations. Making the wrong assumption about just one equation can throw off the entire solution.
- Changing Numbers Between Equations: Some might assume that the values of the objects change between equations. However, in this puzzle, the values stay constant throughout all the equations.
If you’ve made any of these errors, don’t worry! The solution is broken down into clear steps. Let’s work through it together.
Step-by-Step Breakdown: Solving the Puzzle
Let’s start by solving for the Wrench using the first equation:
Equation 1:
Wrench + Wrench + Wrench = 15
This simplifies to: 3 × Wrench = 15
Now, divide both sides by 3: Wrench = 5
So, the value of the Wrench is 5.
Solving for the Gear:
From the second equation:
Wrench + Gear + Gear = 25
We know Wrench = 5, so we substitute that into the equation:
25 = 5 + 2G
Now, subtract 5 from both sides:
2G = 25 – 5
2G = 20
Divide both sides by 2 to solve for G (Gear):
G = 10
So, the value of Gear = 10.
Solving for the Bolt:
From the third equation:
Gear – 2 Bolts = 8
Now that we know Gear = 10, substitute that into the equation:
8 = 10 – 2B
Subtract 10 from both sides:
-2B = 8 – 10
-2B = -2
Now, divide both sides by -2 to solve for B (Bolt):
B = 1
So, the value of Bolt = 1.
Final Step: Solving the Last Equation
Now we’re ready to solve the final equation:
Bolts + Wrench × Gear = ?
We know:
- Bolt = 1
- Wrench = 5
- Gear = 10
Substitute these values into the equation:
1 + (5 × 10) = ?
First, multiply:
1 + 50 = ?
Now, add:
1 + 50 = 51
So, the missing number is 51!
Step 4: Solving the Complete Equation
We need to solve the equation:
Bolt + Wrench × Gear = ?
From our previous steps, we know:
- Bolt = 1
- Wrench = 5
- Gear = 10
Now, substitute these values into the equation:
1 + 5 × 10
Applying the Order of Operations (PEMDAS/BODMAS)
- PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
- BODMAS (used in some regions) follows a similar structure but refers to Brackets, Orders, Division and Multiplication, Addition and Subtraction.
According to this rule, multiplication comes before addition. So, we first calculate:
5 × 10 = 50
Then, we add the Bolt value:
1 + 50 = 51
Final Answer:
The missing number is 51!
Absolutely! You nailed it! The answer is 51, and your approach was spot on. Well done for sticking with it and applying the order of operations correctly. Puzzles like these are great for sharpening your brain and testing your logical reasoning skills.
