Understanding Integers and Their Order
Integers are your everyday whole numbers, but they come in three flavours: positive (like 5, 22, 100), zero, and negative . Think of them as the complete family of numbers without any messy decimal points or fractions.
You can arrange integers in two ways that'll be dead useful for your exams. Ascending order means putting numbers from smallest to largest – imagine climbing up a ladder where each step gets bigger. For example: -11, -3, 15, 34, 101.
Descending order works the opposite way, going from largest to smallest like walking down stairs. Here's what it looks like: 9, 3, 0, -5, -16. Remember, negative numbers get "smaller" as they move further from zero.
Place value is brilliant once you get it – each digit's position determines its worth. In the number 6575, the first 6 represents 6000 (thousands), the 5 means 500 (hundreds), the 7 equals 70 (tens), and the final 5 is just 5 (ones).
Top Tip: When ordering negative numbers, remember that -2 is actually bigger than -10 because it's closer to zero on the number line!

Working with Number Lines and Integer Rules
The number line is your best mate for visualising integers – it's like a ruler that extends in both directions from zero. Negative numbers live to the left of zero, whilst positive numbers hang out on the right. This visual tool makes adding and subtracting integers much clearer.
Here's where things get interesting: multiplying and dividing integers follows specific rules that are actually quite logical. When you multiply two positive numbers or two negative numbers, you always get a positive result. But mix a positive with a negative, and you'll always get negative.
The same pattern works for division – positive ÷ positive = positive, negative ÷ negative = positive, but positive ÷ negative = negative and negative ÷ positive = negative. Once you memorise these rules, integer calculations become much simpler.
Comparison symbols help you make mathematical statements that are either true or false. You've got < (less than), > (greater than), = (equal to), ≤ (less than or equal to), and ≥ (greater than or equal to). These symbols are essential for solving inequalities and comparing values.
Memory Trick: Think of the inequality symbols as hungry crocodiles – they always want to eat the bigger number, so their mouth opens towards the larger value!
