What you need to learn in this chapter
In this chapter, we will be learning about basic operations in mathematics. We will start with addition within 10,000, where we will solve number sentences by adding two or three numbers together. Next, we will move on to subtraction within 10,000, where we will solve number sentences by subtracting two numbers or subtracting two numbers from another number. After that, we will learn about multiplication within 10,000. We will solve number sentences by multiplying different numbers together, including one-digit numbers, 10, 100, and 1000. Lastly, we will study division within 10,000. We will solve number sentences by dividing different numbers by one-digit numbers, 10, 100, and 1000.
