This is the first use of the minus sign we all learn in kindergarten or first grade – i.e. to denote the difference or how far a value is from another. As a difference operator, the minus sign takes in two arguments (10 and 7) and produces one output (3). In this sense, the use of a dash symbol is most obvious, as we would often define source-desti...
The second time we see the minus sign is when we learn about negative numbers or numbers that are on the left side of the zero on the number line. Here, we are not viewing the negative numbers as “reflection” of the positive numbers yet. They are just numbers that extends the positive number line we were familiar with and which are progressing left...
Soon after we learn about negative numbers, we would learn about the third meaning of the minus sign – the “flip” over zero. For a positive quantity or expression, the minus sign flips it across zero on the number line. This time, as a flip operator, the minus sign takes in only one argument (10-7) and produces one result -(10-7). We can concatenat...

Mar 12, 2024 · The minus symbol (-) signifies subtraction. When you're subtracting one number from another, place the minus sign between them. For instance, 6 - 3 shows that you're subtracting 3 from 6. As with the plus symbol, you can place the minus symbol in front of a number to show that it has a negative value.
