Not allowed to use calculator
Hi All, what a great Friday Morning
I am not allowed to use a calculator(could however) but for a Paper I am doing, I need to Multiple 39.6 by 49.5 and show all the long calculations for it.
I already did the approx one and got 2000, but how do I multiple the decimals and add them in and record it all down?
Any suggestions would be very beneficial.
