Number operations are like fun games we play with numbers.

Addition is when you put two or more numbers together. For example, if you have 2 apples and you get 3 more, you have a total of 5 apples. That's addition!

Subtraction is when you take away one number from another. For example, if you have 5 apples and you eat 2, then you have 3 apples left. That's subtraction!

Multiplication is when you repeat a number a certain amount of times. For example, if you have 3 balls and you want to give one to each of your 3 friends, you multiply 3 by 3 and you get 9 balls total. That's multiplication!

Division is when you split a number into equal parts. For example, if you have 12 candies and you want to divide them evenly between 4 friends, each friend will get 3 candies. That's division!

These are the basics of number operations and they are like building blocks for more complex math problems. It's important to practice them and have fun with numbers!
