When you are setting row value with a button, the parenthesis are ignored in calculating the value.

This means that if you want to set the value to `(5-1)/4`

the result will be **4.75 and not 1** as it should be.

Obviously, this isn’t a problem when using static numbers, but the same happens when you replace those numbers with other formulas.

This is a very serious issue which should be fixed as soon as possible.

If I were to guess, I would say this is because button actions are converted into “parse later” and during that conversion the parenthesis are being skipped.

**Workaround**

Transforming your equations into their expanded form (so the formula would be `5/4-1/4`

) should fix the issue. You can even use wolfram alpha for complex formulas.

Another, slightly better workaround would be to replace all `()`

with `Sum()`

.

And here is a proof that this bug is actually real:
