Subtraction: what is subtraction in math

Subtraction is an arithmetic operation that involves finding the result of subtracting one number (the minuend) from another number (the subtrahend). The result is called the difference.
For example, if you have 10 apples and you give away 3 of them, the remaining number of apples is the difference between 10 and 3, which is 7. Mathematically, we can represent this as:
10 – 3 = 7
Here, 10 is the minuend, 3 is the subtrahend, and 7 is the difference.

Subtraction: what is basic subtraction

Basic subtraction is an arithmetic operation that involves finding the difference between two or more numbers. It is one of the four fundamental operations in mathematics, along with addition, multiplication, and division.
To perform basic subtraction, you start by aligning the numbers to be subtracted vertically. Then, you subtract the digits in each column, working from right to left. If the digit on top is greater than the digit below it, you can subtract without borrowing. However, if the digit on top is less than the digit below it, you need to borrow by subtracting 10 from the digit to its left and adding 10 to the digit being subtracted.
For example, let’s say we want to subtract 7 from 15. We would align the numbers vertically and subtract the digits in each column:

“`
15
– 7
——-
“`

The digit in the ones place is 5, which is greater than 7, so we can subtract directly:

“`
15
– 7
——-
8
“`

Therefore, 15 minus 7 equals 8.
