Compare and order integers
Key Notes:
⏱️Positive numbers are greater than 0. ⏱️Negative numbers are less than 0. |
= | When two values are equal, we use the “equals” sign | example: 2+2 = 4 |
---|---|---|
< | When one value is smaller than another, we can use a “less than” sign. | example: 3 < 5 |
> | When one value is bigger than another, we can use a “greater than” sign | example: 9 > 6 |
How to compare and order integers? |
Integers on the left side of 0 on the number line get smaller as we move from right to left, whereas integers on the right side of 0 get greater as we move from left to right. Therefore, to compare two integers, we can use greater than (>) or less than (<) symbols.
How to order the integers from lowest to highest? Give an example. |
The ordering of integers can be done from lowest to highest in ascending order. For example, if we integers such as, 5, -1, 0, 3, -4, -6, 1, 2, then the order of the given integers from lowest to highest will be:
-6 < -4 < -1 < 0 < 1 < 2 < 3< 5
Which is the smallest and largest integers among the ordered integers of -5 to 5? |
If the integers are ordered from -5 to 5, then;
-5 < -4 < -3 < -2 < -1 < 0 < 1 < 2 < 3 < 4 < 5
Thus, from the above arrangement, we can say the smallest integer is -5, and the greatest integer is 5
Rules for Comparing Integers |
Situation | Rule | Example |
---|---|---|
Comparing a positive and negative | Positive is always greater | 3 > -2 |
Comparing two negative numbers | The one closer to 0 is greater | -2 > -5 |
Same number | They are equal | -4 = -4 |
Positive numbers | Higher number is greater | 7 > 3 |
Negative numbers | Smaller absolute value is greater | -1 > -6 |
Ordering Integers |
To order integers means to arrange them from:
- Least to greatest (ascending order)
- Greatest to least (descending order)
🔸 A. Ascending Order: |
From smallest to largest
➡️ Example:-8, -3, 0, 4, 7
🔸 B. Descending Order: |
From largest to smallest
➡️ Example:7, 4, 0, -3, -8
🧾 Real-Life Examples of Comparing Integers |
- Temperature:
5°C > -2°C
→ Warmer temperature is greater - Bank Balance:
₹200 > ₹-100
→ Positive balance is greater than debt - Elevation:
Sea level (0 m) > Mount basement (-100 m)
Step-by-Step Process to Compare and Order |
✅ Comparing Two Integers:
- Look at the signs (positive or negative).
- Use a number line if needed.
- Apply the rule: further right = greater.
✅ Ordering Multiple Integers:
- Plot them mentally (or on a number line).
- Identify the smallest and largest.
- Arrange them based on ascending or descending need.
🔍 Examples |
Example 1:
Compare: -4 __ -7
👉 Rule: -4 > -7
(since -4 is closer to 0)
✅ Answer: -4 > -7
Example 2:
Order in ascending: 3, -5, 0, -2
✅ Step: -5, -2, 0, 3
Example 3:
Order in descending: -8, 4, -1, 0
✅ Step: 4, 0, -1, -8
🧠 Extra Practice Problems |
- Compare:
a)5 __ -3
b)-2 __ -9
c)0 __ -1
- Arrange in ascending order:
-6, 3, 0, -1
- Arrange in descending order:
-4, -9, 2, 0, 5
- Which is greater?
a) A depth of-15 meters
or-8 meters
b) A temperature of-5°C
or2°C
🎯 Key Takeaways |
- Integers can be positive, negative, or zero.
- Right on the number line = greater
- Negative numbers with smaller absolute value are greater.
- Use <, >, = to compare.
- Use ascending/descending for ordering.
