You might think it's not important to know that 2, 4 and 6 are even numbers. This is true when doing simple calculations such as 6 + 3. Whether they are odd or even has little bearing on the sum. However, if you want to go into a career where a thorough understanding of math is vital ~ and there are plenty of them ~ you'll need to know a lot more about numbers than how to do basic calculations.

They are all whole even numbers and multiples of 2
|
They are all whole odd numbers, and each number is two more than then previous number

You can cancel the zero in the number with the zero in ten and write the answer straight away, e.g. 120 ÷ 10 = 12

If a number is a multiple of another number, then it divides the other number exactly a certain number of times, e.g. 4 divides 48 exactly 12 times because 12 × 4 = 48. Note: 2.8 is a multiple of 16.8 because 2.8 × 6 = 16.8: so the idea of 'multiples' also applies to decimal numbers

For example: 6 + -5 = 1 (a positive number); 6 + -7 = -1 (a negative number); 6 + -6 = 0 (zero). DON'T forget zero - it is a number
|
A square number is formed by multiplying another number with itself : 64 = 8 × 8; 121 = 11 × 11; 81 = 9 × 9. Note: 1 × 1 = 1

Not so, e.g. 2 × 9 = 18 BUT 18 is NOT divisible by 4. If you want to show that a statement is not always true, find one example that shows it is wrong - like we did here
|
Not so! For every positive number there is a negative number, e.g. 2 and -2, 1,000 and -1,000, 3.4 and -3.4: this goes on and on without end for every number you care to think of

For example, 130 (ends in zero) and 345 (ends in five) are both divisible by 5
|
Doubling an odd number will always produce an even number
