Decrease the value of a variable by xx (calculate with MacroDroid) (SOLVED)

[Endscreen]

I want to subtract a two-digit value from an integer variable (example: 20)
int_x-pos 420 - 20 > save to int_x-pos

I only found a way to increase or decrease the value by 1

At the bottom of list there is also 'Expression' (when configuring set variable action) so you just put there {v=int_x-pos}-20 (or lv instead v if its local variable) to set it to current variable's value-20

A bit complicated to explain but I found it. Thanks for your help.
