Subtraction is a mathematical operation that involves taking away one number from another. It is the inverse or opposite operation of addition.
Minus numbers, also known as negative numbers, are numbers less than zero. They are represented by a minus sign (-) in front of the number.
To perform subtraction, you start with the larger number and take away the smaller number from it. For example, to solve 7 - 3, you would start with 7 and take away 3, which equals 4.
The main difference between subtraction and addition is that subtraction involves taking away or removing a quantity, while addition involves combining or adding a quantity.
One way to better understand subtraction is to practice using it with real-life examples. You can also use visual aids, such as number lines or manipulatives, to help conceptualize the process of taking away or removing a quantity.
