\nWhen rounding to a given number of decimal places, do the following:
\nLook at the next number after the last number of the decimal places you need to round to.
\nIf the number is 5 or greater, round up, if it is than 5, leave as is.
\nFor example, round the following to 3 decimal places...
\n$0.0055 = 0.006$
\n$0.0071 = 0.007$

\nWhen rounding to a given number of significant figures, do the following:
\nLook at the next number after the last number of the significant figures you need to round to.
\nIf the number is 5 or greater, round up, if it is than 5, leave as is.
\nRemember to keep the number you rounded to the significant number of places in the same unit e.g. 10's, 100's etc
\n\nFor example: rounding the following to 3 significant figures...
\n$2573 = 2570$
\n$7828 = 7830$
\nor the following to 1 significant figure...
\n$15 = 20$
