What rules are applicable to subtracting two values that have different numbers of decimal places for example subtracting 2.1 from 2.15?

When subtracting numbers, the numbers need to be aligned in place value columns. The easiest way to do this is to align the decimal points. If one number has less digits after the decimal point then extra zeros can be added to the end of the number to make it the same length as an empty place value column is the same as one with a zero in it (zero was originally first used to indicate an empty place value column). So for 2.15 - 2.1 the decimal points need to be aligned: _____2.15__ _____2.1___ But to make the subtraction easier, adding extra zeros after the 1 of 2.1 to make the 2.1 the same length as the 2.15 (ie upto the hundredths digit) helps: _____2.15___ _____2.10___ Now you can easily do the subtraction: _____2.15___ _____2.10___ _____-----____ _____0.05____ _____===____ This trick of appending extra zeros is very useful if the first number has less digits, eg 2.2 - 2.15: _____2.2_____ _____2.15____ Becomes: _____2.20____ _____2.15____ Which is easier to do, giving: _____2.20____ _____2.15____ _____-----_____ _____0.05____ _____===_____

What is the difference between adding and subtracting?

Adding is when you add numbers to something and subtracting is when you take them away. When you add you do not always make the number go up for example 5 + (-7)= -2.


How do you explain adding and subtracting negative numbers?

Adding a negative number is equivalent to subtracting a positive number. For example, adding -3 is the same as subtracting 3. Subtracting a negative number is equivalent to adding a positive number. For example, subtracting -3 is the same as adding 3. The rule to remember is that when you have a negative sign in front of a number, it actually changes its sign.

When adding or subtracting measured quantities what determines the number of decimal places?

I presume this is a question about scientific arithmetic. When adding or subtracting two numbers, with a different number of decimal places, the quantity with the least number of decimal places determines the number of decimal places in the answer. For example, let's say you are adding two masses: .1 grams .11 grams .1grams + .11grams = .21 grams Because .1 only has one decimal place, the answer becomes .2 grams, and we ignore the .01 because it is lost due to a lack of precision. The process of multiplying and dividing is different, as you compare significant digits instead of decimal places instead.


When subtracting one decimal fraction from another and one has more decimal places than the other what should you do?

Step 1. Align their decimal places then do the subtraction. Example 1: 1234.567-123.3 1234.567 -123.3 ------------- 1111.267 If the minuend has lesser decimal places, add zeros after the last decimal point so that it will have the same decimal places as the subtrahend. Then do step 1. Example 2: 1234.5 - 123.456 1234.500 -123.456 ------------- 1111.044

How do you subtract decimals?

align the decimals and subtract as you normally would. make sure after subtracting you bring the decimal down. replace empty space with zeros. for example: 1.340 - 1.3250 will look like this 1.340 - 1.3250 another example: 10.39485 - 9.847 will look like this. 10.39485 - 9.84700 <----see how I added zeros. When your done subtracting, you bring the decimal straight down to your answer. 7.584 - 5.483 _________ 2.101 SORRY, WHEN I POSTED IT MOVED ALL THE NUMBERS AND TRIED TO RE-POST TO GET THEM TO ALIGN


What is the answer of binary decimal plus binary?

If you want to add numbers in different bases, in this case decimal and binary, or do any other calculation that involves different bases for that matter, you have to convert all numbers to a single system first - for example, all to decimal. Then you can do the operation. It is really up to you in what base you represent the final answer. In this example, you can convert back to binary, for example.


What is the rule for subtracting negative numbers?

How do you subtract sig figs?

When subtracting (or adding), the answer should have the lowest number if decimals of any number in the problem. For example, 25.1 + 55.89 + 23.321 should equal 104.3 because 25.1 has only one decimal point.


How can you use invers operations to chek your answer to a decimal subtracions problem?

Add the result of the subtraction to the number you were subtracting and you should get the number from which you subtracted. example 246.8 - 35.15 = 211.65 To check add 211.65 + 35.15 and see if you get 246.8

What is computer math?

computer maths are the operations of adding or subtracting binary, octal or hexadecimal numbers. These operations are normally carried out while programming in assembly language. A very simple subtraction example: Take a binary number of say 1111 (equivalent to 15 in decimal) minus 0010 (equivalent to 2 in decimal) results in 1101 (equivalent to 13 in decimal).
