Negative numbers are mainly used with coordinates and temperature. Use negative numbers in addition and subtraction problems including subtracting a negative number.

The distance, speed and time equation allows us to calculate distance, speed and time. In all of these calculations, the units used should correspond with each other.

Many calculations result in solutions to a greater degree of accuracy than what is required. In such cases the answers are rounded to the required degree of accuracy.

Select and carry out calculations and round answers to the nearest significant figure. A way of approximating or estimating an answer is to round off using significant figures.

Calculations can be carried out using fractions of shapes and quantities. Mixed fractions can be added or subtracted to find the number of fractional parts in a mixed number.

Calculations can be carried out using percentages of shapes and quantities. We can calculate percentage increase and decrease, as well as express a quantity as a percentage of another quantity.

A ratio is used to compare two quantities which are measured in the same units. Given a ratio, quantities can be calculated.
