Yes you can. They are called matrices. Easy to do I used translation for this so sorry if it is hard to understand.
{ 4 7 } { 8 5 }
{ } { }
{ } { }
{ 3 9 } { 2 4 }
Simply multiply across so from the first box to the second 4*8.....etc. Easy to put on a calculator. And let's say there was a imaginary number in front of the first box you would multiply or divide from whatever is by it. So here an example using multiplication. ?*4*8= and you'll so this for the rest of them so they'll look like this.. and if there was an imaginary number you'd slide it in as so. No need for a calculator unless it's to the supreme! Like 12.789 *4*7/9* 12.00/PI
4*8
7*5
3*2
9*4
