- Rounding
-Worded Problems
Jane Stratton
Objectives:
• To review basic number skills that will be required throughout this unit
• To review mathematical language used in this unit
This unit assumes that you have some basic maths skills already
If you have difficulty with any of the following topics please talk to your lecturer/tutor for advice
The following slides will be available on MyLO you do not need to copy them down, but a list of the skills we assume you already have might be useful in case you need to revise them!
How to ‘talk’ mathematics
• Remember, no matter what subject you are studying, half the battle is learning the language of that subject.
• Once you learn the language of a subject you will sound like
(and be) an expert!
• Example:
Take this quote from a popular ‘non-animated feature-length theatrical release’ (yes that means a movie!)
“I'm disinclined to acquiesce to your request”
(…translated as ‘NO’!)
You’re sounding like an expert already!
Remember these terms from last time?
Now it’s time for more….
Examples of Mathematical Language…
• Natural Numbers
(counting numbers)
– The set of natural numbers is {1, 2, 3, 4, 5, …}
• Whole Numbers
(not fractions or decimals)
– The numbers in the set {0, 1, 2, 3, 4, 5, 6, 7, . . . . } are called whole numbers.
• Integers
(whole numbers including those with a negative sign)
– The set of integers extends the set of whole numbers to include negative numbers {…, -3, -2, -1, 0, 1, 2, 3, …}
– The integers give us answers to questions like: ‘What can I add to 5 to get 3?’
• Rational Numbers (integers AND fractions AND decimals)
– Numbers that can be written as fractions or a repeating or terminating decimal.
• Irrational Numbers (don't include integers OR fractions)
– Cannot be written as a fraction, they have a decimal form that is non-repeating and has no pattern e.g. Pi = 14159265358979323846264338327950…
