|Damaged calculator (Posted on 2019-05-07)
I have a strange calculator. The four elementary calculations +, -, *, / are not available, but there is a button (called OMG) which has the following property: if you enter the number a, press OMG, and enter the number b then the result shown on the screen is 1-a/b. The change signs button and the calculator's memory are functioning normally, as are all the numbers from 0 to 9.
Is it possible to calculate the expression ((2018+2019-2020)*2021)/2022 using the calculator only?
EDIT: You MUST only use the calculator to calculate the expression! (i.e. you must perform the calculation 2018+2019, then subtract the answer by 2020, etc., using only buttons on the calculator). You cannot simplify the expression beforehand!
