Interpret the type of correlation: calculate the correlation coefficient r rounded to the nearest three decimal places. Interim rounding should be four decimal places.

r=10?6437-(? 72)(?843) / ?10?550-(? 72)^2 ?10?843-(? 72187)^2

Would someone please help me with this. Thank you!! :)
 
I don't understand how to work it. Do I multiple all by 10 and then divide?
