It depends on what problem 4 is.
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
None, because the set of integers and the set of whole numbers is the same.
All whole numbers are decimal numbers.
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.
add? dont you mean subtract?
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.
Whole Numbers
Adding decimal same as adding whole numbers
Very.
Because if you dont , your answer will be a whole number and that will make your answer wrong
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.
they are both the same because you get the same answers you just drop the $ sign. Ex. $3.56+$1.50=$5.06 and 3.56=1.50=5.06
