Question
what is this type of problem called? 7+7 = 19 - 5
Answers

The type of problem you've presented, where both sides of an equation seem to suggest different mathematical validity, can be referred to as a **numerical or mathematical puzzle**. In this specific case, it is essentially an equation that is incorrect because \( 7 + 7 \) equals \( 14 \), while \( 19 - 5 \) also equals \( 14 \).
You might also encounter such problems in the context of brain teasers, trick questions, or mathematical reasoning exercises, where the objective is to examine the validity or find a solution to equations that appear misleading at first glance. Another related concept is an **equation balancing problem**, where the challenge involves making both sides equal through manipulation or analysis.

It sounds like you might be talking about a type of mathematical reasoning or logic puzzle involving equations that appear to be incorrect. If you’re looking to solve or analyze the equation \( 7 + 7 = 19 - 5 \), here’s how you could approach it:
1. **Calculate Each Side**:
- Left Side: \( 7 + 7 = 14 \)
- Right Side: \( 19 - 5 = 14 \)
2. **Compare Both Sides**:
- Since both sides equal \( 14 \), the equation is actually true but may have appeared misleading initially.
3. **General Approach for Similar Problems**:
- **Identify each mathematical operation** involved on both sides of the equation.
- **Calculate** the values resulting from these operations.
- **Compare the results** to seek equality or uncover any mistakes.
- Consider rearranging or manipulating the equation if necessary to test if it holds under different circumstances.
### Example Problem-Solving Steps:
- Example equation: \( a + b = c - d \)
- If given specific values, replace them in the equation and solve for unknowns.
- Ensure to work step-by-step to systematically verify or disprove equality.
### Further Context:
If this type of problem was meant as part of a specific puzzle or game format (like a programming challenge or a brain teaser), the method might vary slightly based on the rules of that specific format. In any case, breaking down the operations, recalculating, and systematically checking for logical consistency will always be a good approach.

Not a way to write 52 + 80 and why
50 + 2 + 80
(50 + 80) + 2
50 + 80 + 2 + 8
50 + 2 + 80 + 0
50 + 2 + 80
(50 + 80) + 2
50 + 80 + 2 + 8
50 + 2 + 80 + 0

The equation \(52 + 80\) can be represented using different expressions to illustrate how the sum can be manipulated by breaking down or regrouping the numbers. Here’s how to write \(52 + 80\) in the forms you provided and an explanation of each:
1. **\(50 + 2 + 80\)**:
- Here, \(52\) is decomposed into \(50 + 2\). This is a simple way to express \(52\) by separating it into tens and ones.
2. **\((50 + 80) + 2\)**:
- This representation uses parentheses to group \(50 + 80\). First, you would add \(50\) and \(80\), which equals \(130\), then you add \(2\) to get \(132\). This just shows a different order of addition (using the associative property).
3. **\(50 + 80 + 2 + 8\)**:
- This expression rearranges the numbers but also adds \(8\) to the original values to total \(140\). However, in relating this back to \(52 + 80\), the extra \(8\) throws off the equation, making it incorrect as a direct representation of \(52 + 80\).
4. **\(50 + 2 + 80 + 0\)**:
- This is also a valid representation because adding \(0\) does not change the value. It equates to \(132\) and is effectively another way of breaking down \(52\) and including \(80\).
### Summary
While expressing \(52 + 80\) as \(50 + 2 + 80\) and \((50 + 80) + 2\) is valid, the equations \(50 + 80 + 2 + 8\) and \(50 + 2 + 80 + 0\) do not represent \(52 + 80\) accurately in the context of maintaining equality. Each rewritten form can show different aspects of the numbers involved, and although they can highlight interesting properties of addition, it's important to ensure that they still equal \(132\) when evaluated. In the context of your examples, only certain rearrangements preserve the direct equivalence to \(52 + 80\).
