Integers are whole numbers, both positive and negative. Therefore, adding and subtracting integers would be adding and subtracting whole numbers. Examples: 8+2 -8+2 8-2 -8-2

Adding decimal same as adding whole numbers

Really? whole numbers are like dollar bills. if there is no change then $1.00 can be just $1 a whole number, no decimals, and so can all other total dollar amounts.

Because if you dont , your answer will be a whole number and that will make your answer wrong

adding fractions is like adding a WHOLE lot of parts of numbers

When you are adding and subtracting decimals, youare +/- ing the whole numbers and tenths in the number. the decimal might go away ex: 1.3-0.3=1 or it won't ex: 1.9-0.3=1.6

by adding, subtracting, dividing, and multiplying.

I would think that the commonality of adding and subtracting integers is that the answer itself will always be an integer. In other words, the answer is always gonna be a "whole number".

You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.

None, because the set of integers and the set of whole numbers is the same.

when you add mixed numbers you have a whole number but adding fraction does not.

You are working with numbers. One is a whole number and the other is a fraction of a whole number (with a decimal point, etc). You apply the same principles of subtracting one number from another or a fraction of one number from a fraction of another. Numbers is numbers!

a mixed number is a whole number with a fraction, ie. 2 3/4 Adding mixed numbers involves adding the whole numbers, then adding the fractions, then reducing the fraction and if it is improper, changing it to a whole number with a fraction and adding that whole number to the other whole number answer.

Integers include 0, the negative numbers without fractional parts, and the positive numbers without fractional parts. The "without fractional parts" part of the description implies that all of the integers are whole numbers. Therefore, if you are adding integers, you are adding whole numbers.

add? dont you mean subtract?

It depends on what problem 4 is.

the same as adding whole numbers. two negatives = negative. two positives = positive, and a negative and positive depends on the absolute value of the greater number.

It can be same because it,s just the decimal

Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept together, same for the hundredths, and so on.

Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.

46 3/4 - 27

You will probably get the wrong answer. Pay attention!

Math concepts include the following: Fractions (half and whole numbers), geometry (study of different shapes), functions (adding, subtracting, multiplying and dividing) and other pre-algebra topics

Hey awesome Question. The answer is no you do not have to line up the decimals when multyping only when adding and subtracting. The main thing is when you multiply make sure you put the decimal in the right place in your answer. YOu count how may places their are behind the decimals in BOTH numbers then you make sure their are that many places behind the decimal in you answer. :)

13% is a fraction and you cannot represent it as a whole number. You can convert it to a whole number by adding, subtracting, multiplying or dividing (or other operations) but that would not be the same number then.
