====Specification====

**N13** 
use standard units of mass, length, time, money and other measures (including standard compound measures) using decimal quantities where appropriate

**N14** 
estimate answers; check calculations using approximation and estimation, including answers obtained using technology

**N15** 
round numbers and measures to an appropriate degree of accuracy (e.g. to a specified number of decimal places or significant figures); use inequality notation to specify simple error intervals due to truncation or rounding

**N16** 
apply and interpret limits of accuracy, including upper and lower bounds
