So I understand that I convert the numbers into rational expressions and then multiple them...
which simplifies to...
2 x x 3
which equals 36.
but how do I multiply these numbers without a calculator? lol... Maybe I don't even really need to know, but I'm expecting to take a placement test when I reenter university after severals years of not having to do this stuff and I'm concerned they may expect me to know how to multiply rational expressions without a calculator.
I don't know what this process or procedure is called and I can't find any clear examples in my text book.
