> 2x +3 = 7. Solve for x.

> To solve this equation, we need to isolate the variable on one side of the equals sign. To do this, we can subtract 3 from both sides of the equation to get 2x = 4. Then, we can divide both sides by 2 to get x = 2. Therefore, the solution to the equation is x = 2.

Depends on the kind of math, it can do basic things reasonably consistently, but for other things it will confidently respond with the wrong answer (e.g. matrix arithmetic). In my testing, I found that it will absolutely fail every time at tasks like "sum the digits of the number 1283892"
