📚 Topic Summary
Subtraction number sentences are like math stories that show how we take away one number from another. They use symbols like the minus sign (-) and the equals sign (=) to show the whole problem in one line. For example, $5 - 2 = 3$ is a subtraction number sentence. It tells us that if we start with 5 and take away 2, we are left with 3. These sentences help us understand and solve subtraction problems easily.
