If you want to use a number line to add and subtract, it can be done with a slide rule. But it is much easier to use an electronic calculator.
You add or subtract (or use other operators) depending on what is required.
To subtract a positive number, you go the specified number of units to the left. To subtract a negative number (which is the same as adding the corresponding positive number), you go to the right.
First, subtract the absolute values of the integers, then use the greater absolute value's sign.
A number line can be a helpful visual tool for adding and subtracting like fractions. To add fractions, start at the point representing the first fraction, then move to the right by the value of the second fraction. For subtraction, begin at the first fraction and move to the left by the value of the second fraction. Since the fractions have the same denominator, the movements on the number line will reflect the sum or difference of the numerators while keeping the denominator constant.
To add integers without a number line, you can use the concept of combining positive and negative values. Start with the larger absolute value and determine the sign based on which number has the larger absolute value. For example, if you're adding -3 and +5, subtract the smaller absolute value (3) from the larger (5) to get 2, then apply the sign of the larger number, resulting in +2. This method effectively simplifies the addition process.
we can use the number line as a model to help us visualizeadding and subtracting of signed.

use the number line
All you do is find the largest and smallest number in the data. Then you subtract the small number from the big number.
To subtract a positive number, you go the specified number of units to the left. To subtract a negative number (which is the same as adding the corresponding positive number), you go to the right.
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
You would use a - to subtract a number on a spreadsheet
First, subtract the absolute values of the integers, then use the greater absolute value's sign.
You can add or subtract it as a whole number. If you must use its decimal form, you just stick a decimal point at the end the whole number!
it is important to learn how to add and subtract fractions because we can use it when a time comes , when we have our own business and others .

2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.
