Why Do We Need Negative Numbers?
Let's discover why negative numbers exist
through weather!
Temperature is the perfect way to understand positive, negative, and
zero!
+25°C
Hot Weather
When temperature is above freezing, it's positive!
"25°C above freezing" = +25 Perfect for swimming! 🌞
0°C
Freezing Point
When water starts to freeze, it's zero!
"Exactly freezing" = 0 Ice begins to form! ❄️
-10°C
Cold Weather
When temperature is below freezing, it's negative!
"10°C below freezing" = -10 Very cold winter day! 🥶

Learning Comparators: Understanding >, =, <
Let's learn how to compare numbers using the comparison operators!
Important: When the weighing machine is lower, it
means the number is greater!
>
Greater Than
The > symbol means "greater than"
Example: 5 > 3 The left number is bigger than the right
=
Equal To
The = symbol means "equal to"
Example: 4 = 4 Both numbers have the same value
<
Less Than
The < symbol means "less than"
Example: 2 < 7 The left number is smaller than the right

Associative Property - Addition
Let us add the first two terms.
Let us evaluate [(-24) + (-11)]
[(-24) + (-11)] + (-1)
1
2
3
Step 1: Solve the bracket
[(-24) + (-11)] =
Step-by-step: Since both numbers are negative [(-24) and (-11)], ignore the
signs first and add the numbers: 24 + 11. Then, put the negative sign (-)
back on the result.
Step 2: Add the third term
(-35) + (-1)
=
Step-by-step: You are adding two negative numbers again. Add the value
35 to 1, and keep the negative sign for your final answer.
[(-24) + (-11)] + (-1) =
-36
Let us evaluate [(-11) + (-1)]
(-24) + [(-11) + (-1)]
1

3
Step 1: Solve the bracket
[(-11) + (-1)] =
Add the magnitudes: 11 + 1 = 12. Both numbers are negative, so the result is -12.
Step 2: Add the first term
(-24) + (-12)
=
Add magnitudes: 24 + 12 = 36. Both are negative, so result is -36.
(-24) + [(-11) + (-1)] =
-36
-36
=
-36
You made it look easy!
Do you see that grouping the integers differently does not affect the result of the addition? Associative property holds good for addition of Integers.
Associative Property - Subtraction
Is [(-1) - (-14)] - 9 = (-1) - [(-14) - 9]
Let us subtract and see what happens.
Let us evaluate [(-1) - (-14)]
[(-1) - (-14)] - 9
1

3
Step 1: Solve the bracket
[(-1) - (-14)] =
Remember: Subtracting a negative is the same as adding a positive.
-1 - (-14) = -1 + 14 = 13
Step 2: Subtract the third term
(13) - 9 =
13 - 9 = 4
[(-1) - (-14)] - 9 =
4
Let us evaluate [(-14) - 9]
(-1) - [(-14) - 9]
1

3
Step 1: Solve the bracket
[(-14) - 9] =
-14 - 9 = -(14 + 9) = -23
Step 2: Subtract from the first term
(-1) - (-23)
=
-1 - (-23) = -1 + 23 = 22
(-1) - [(-14) - 9] =
22

You are a smart kid!
Do you see that grouping the integers differently changes the result of subtraction? Associative property does NOT hold for subtraction of integers.
