Problem: Sean wrote 17 letters. If the number of letters he wrote is equal to the number of letters he wrote yesterday plus 10, how many letters did he write yesterday?

Gemini-1.5 Pro:

Let's use a variable to represent the unknown:

* Let 'x' be the number of letters Sean wrote yesterday.

We know:

* Sean wrote a total of 17 letters.
* This total is equal to the number he wrote yesterday (x) plus 10.

We can set up an equation: 
x + 10 = 17

To solve for x, we need to isolate it.  We can do this by subtracting 10 from both sides of the equation:
x + 10 - 10 = 17 - 10

This simplifies to:
x = 7

### Answer: Sean wrote 7 letters yesterday.

Problem: If you start with the number 6 and want to add a number n to it so that it equals 10, what is the value of n?

Gemini-1.5 Pro:

Reasoning: To find the value of *n*, we need to figure out the difference between 10 and 6. This can be represented by the equation 6 + *n* = 10. Subtracting 6 from both sides of the equation, we get *n* = 10 - 6 = 4. 
### Answer: n = 4

Problem: A robot needs 10 units of energy to start and run for 1 hour, but to keep running for another hour, it needs additional 'w' units of energy. If the total energy required for the robot to run for 2 hours is 13 units, how many extra units of energy does it need to run for the additional hour?

Gemini-1.5 Pro:

Reasoning: After the first hour, the robot has used its initial 10 units of energy. 
To run for a second hour, it needs an additional 'w' units, and the total energy used becomes 10 + w.
Since the total energy for 2 hours is 13 units, we have the equation 10 + w = 13.
Solving for 'w', we get w = 13 - 10 = 3 units.

### Answer: 3 

Expected answer: 3

Problem: John has a guitar with 10 strings. Some of the strings broke, but you know that being left with (e + 6) strings meant the guitar still had 10 strings. What is the value of e, i.e., how many strings were broken?

Gemini-1.5 Pro:

Reasoning: We know that (e + 6) equals the total number of strings, which is 10. 
To find the value of 'e', we need to solve the equation: e + 6 = 10
Subtracting 6 from both sides of the equation, we get: e = 10 - 6 = 4
Therefore, 'e' is equal to 4, which represents the number of broken strings.

Gemini-1.5 Pro:

Reasoning: We need to find the value of 'u' in the equation 10 + u = 16. 
Subtracting 10 from both sides of the equation, we get u = 16 - 10 = 6.
