The basic number operations are addition, subtraction, multiplication, and division.
To add two numbers, you combine them to find the total. For example, 7 + 5 = 12.
Multiplication is a way to add a number to itself a certain number of times. For example, 3 times 4 (3 × 4) means adding 3 four times (3 + 3 + 3 + 3), which equals 12.
Even numbers are divisible by 2 and end in 0, 2, 4, 6, or 8. Odd numbers are not divisible by 2 and end in 1, 3, 5, 7, or 9.
