Fail to parse and verify answer in **xxx**

I encountered this issue when verifying the answer in a format like **answer**

For instance, the gt is 73, and the parsed result (default) is [73, '73'], which is good.

The tail partt of the model-generated answer is:

> ...... - 73 = 489 ...(iii)
>
> Now sum (i)+(ii)+(iii):

> Left: (x_D + x_G + x_S) + 2(y_DG + y_DS + y_GS) = 437 + 2*234 = 437 + 468 = 905

> Right: 122 + 294 + 489 = 905

The parsed result is [234, '73**'], where the ** should not appear right here.

The result of the "verify" function is False, and I guess the reason is because the ** symbol in the parsed result interferes with the verify function's judgment.
