LEARNING OUTCOMES
By the end of this chapter you will have familiarised yourself with the basics of decimals, metric measures, percentages, fractions, ratios and averages.
FEELING A BIT RUSTY?
Don’t worry if picking up this book and the word ‘calculations’ gave you palpitations! We’ll start nice and gently and summarise the basics. You may remember most of this already and feel confident enough to skip the chapter completely, and go straight to the self-assessment test in Chapter 2, or you may need to build up your confidence and reacquaint yourself with the basics.
Symbols and Signs
| + | plus or addition sign; example: 6 + 9 = 15 |
| − | decrease, subtract or minus sign; example: 11 − 4 = 7 |
| × | multiply or ‘times by’ sign; example: 9 × 6 = 54 |

Rounding Decimal Numbers
Sometimes it is necessary to ’round up’ or ’round down’ a decimal number or a whole number. This is particularly true in infusion drip rate calculations, as it is impossible to give a ’point’ or part of a drop when setting an infusion rate; for example, 7.2 drops: how would you get the 0.2? Other medication calculations may need to be highly accurate and incorporate all the ’points’, but as a general rule:
If the number after the point is 4 or less: round down
If the number after the point is 5 or more: round up
This is often known as the ’rule of 5s’.
Therefore, 7.2 drops becomes 7 drops only; 2.8 becomes 3.
I get it! Decimal places are numbers to the right of the decimal point. Example: 5.72 has two decimal p...
