The Problem:

Find x.

(2021)0 +(2022)1 -(2023)x =0

-/|\-

Solution:

An easy one to see the new year in with.
The first term, (2021)0=1 as any number raised to the zeroth power is one (if it's not zero), and
the second term, (2022)1=2022 as any number raised to the power of one is that number.
So, the first two terms sum to

(2021)0+(2022)1=1 +2022=2023


Now our equation simplifies to 2023-(2023)x=0,
and further to (2023)x=2023

Hence, x=1.
