Those are the two

If you left-click on the concerned component input and hover your mouse cursor over Expression, it will show you the formula.

Both times, the used formula is x-1, which means that 1 is subtracted from each value that is input.

Kěnéng nǐ lǐjiě cuò wǒ de yìsile, gōngshì lǐmiàn de X-1 shì wǒ zìjǐ luàn xiě de, wǒ jiù xiǎng zhīdào túpiàn ànlì lǐmiàn de*shì xiě de shì shénme, cáinéng dédào ànlì zhèyàng de jiéguǒ

Maybe you understand what I mean by mistake. The X-1 in the formula is my own scribble. I want to know what the * in the picture case is written in order to get the result of the case.
