To play a game of basketball or football, you need an even number of players.
Ā Ā Ā Ā Ā Even numbers can be divided into two equal groups like 2, 4, 6, 8, and 10.
6 players can split into two equal groups. That's why 6 is an even number!
Every number that isn't even is called odd.
Ā Ā Ā Ā Ā Odd numbers can't be divided into two equal groups. 1, 3, 5 are all odd.
Ā Ā Ā Ā Ā To tell if any number is even or odd, just look at the rightmost digit (š), the Ones place digit.Ā
Ā Ā Ā Ā Ā Numbers that end in 0, 2, 4, 6, and 8 are always even.
Ā Ā Ā Ā Ā Numbers that end in 1, 3, 5, 7, and 9 are always odd.
Think about the number 13. Is it even or odd?
Since 3 is an odd number, the number 13 is odd, too.
All numbers follow these 4 patterns.
Even + Even = Even
Example: 2 + 2 = 4
Odd + Odd = Even
1 + 3 = 4
Even + Odd = Odd
2 + 3 = 5
Odd + Even = Odd
1 + 2 = 3
Just like with addition, there are 4 rules for subtraction. Take a look.
Even - Even = Even
4 - 2 = 2
Odd - Odd = Even
3 - 1 = 2
Even - Odd = Odd
2 - 1 = 1
Odd - Even = Odd
3 - 2 = 1
Great job. š
Now, ace the practice. You'll remember for longer.
