To multiply 36*5.9 one way of doing it without a calculator and in a way that I can show you here you can do. 5.8*36 is the same as saying 36+36 5.9 times so we can first off take 36*5=180 and then to find are .9 part of 36 we would have to take 36*.9=32.4 so now we take 180+32.4=212.4 and that is are end answer.
