The year puzzle is a mathematical game. In this game, the numbers of a year (example: 2020), and mathematical symbols are added to form different numbers.

Examples

These are some answers to the year puzzle; more than one answer was listed for some results, but there may be other possible answers. The calculations in blue use only elementary arithmetic operations, and it is not allowed to combine numbers.

Year 2020

$0=2\times 0\times 2\times 0=(2\pm 0)-(2\pm 0)$

$1=(2\pm 0)÷(2\pm 0)=2^0\times 2^0$

$2=2\pm 0\pm (2\times 0)=2^0+2^0$

$3=2+0!\pm (2\times 0)=(2+0!)\times (2-0!)$

$4=2\pm 0+2\pm 0=(2+0)\times (2+0)$

$5=2+0!+2\pm 0$

$6=2+0!+2+0!$

$7=2^{0!+2}-0!$

$8=2^{0!+2}\pm 0=2^{0!+2\pm 0}$

$9=(2+0!)\times (2+0!)$

$10=20÷(2+0)$
